You have a small typo on line 71. An 'S' is missing in "KEY_PREVIOUSSONG'.

@xrazis: great catch - thank you! Updated ✨

Why are you using "false" on "hires" under "hiresscroll"?

For me it caused the scrolling to be unusable, having to scroll at max speed to create any movement. And the fix for it was setting "hires" to "true"

@ClassyLion: I don't use a HiDPI monitor, so hires=true makes scrolling way too fast for me. hires is a setting that needs tweaked for each individual setup.

I confirm, work on Redhat 8, Thank you for sharing!

switch between windows work only for File Manager, otherways nothing happen.

I'm not sure if this is the right place for this question, let me know if I should move it somewhere else - Is there a way to make "wheel mode switch" one of the gestures in your code? The normal UI doesn't allow it, and it forces you to use up the whole button on that task. Also is there a way to trigger "wheel mode switch" and "toggle smooth scrolling" together in the same action? I find the smooth scrolling useful on freespin mode but not on ratchet mode. Thanks!

Nice gestures for the "Forward" and "Wheel" buttons!
I pulled those gestures to my config.

I also would like to map the scroll wheel in the "Forward" gestures group to volume changes like this:

                    {
                        direction: "ScrollDown";
                        threshold: 1;
                        mode: "OnInterval";
                        interval: 1;
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_VOLUMEDOWN"];
                        }
                    },
                    {
                        direction: "ScrollUp";
                        threshold: 1;
                        mode: "OnInterval";
                        interval: 1;
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_VOLUMEUP"];
                        }
                    },

This mapping works on the M720, but does not work on MX Master 3 for some reason (I hadn't debugged this yet).

I have mappings for thumb gesture button for windows operating (maybe someone will like it):

        {
            # Thumb Gesture button
            cid: 0xd0;
            action: 
            {
                type: "Gestures";
                threshold: 50
                gestures: (
                    {
                        direction: "Up";
                        mode: "OnInterval";
                        interval: 150;
                        action:  {
                            type: "Keypress";
                            keys: ["KEY_LEFTALT", "KEY_LEFTSHIFT", "KEY_TAB"];
                        };
                    },
                    {
                        direction: "Down";
                        mode: "OnInterval";
                        interval: 150;
                        action:  {
                            type: "Keypress";
                            keys: ["KEY_LEFTALT", "KEY_TAB"];
                        };
                    },
                    {
                        direction: "Left";
                        mode: "OnInterval";
                        interval: 150;
                        action:  {
                            type: "Keypress";
                            keys: ["KEY_LEFTCTRL", "KEY_LEFTSHIFT", "KEY_TAB"];
                        };
                    },
                    {
                        direction: "Right";
                        mode: "OnInterval";
                        interval: 150;
                        action:  {
                            type: "Keypress";
                            keys: ["KEY_LEFTCTRL", "KEY_TAB"];
                        };
                    },
                    {
                        direction: "ScrollDown";
                        threshold: 1;
                        mode: "OnInterval";
                        interval: 1;
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_LEFTCTRL", "KEY_MINUS"];
                        }
                    },
                    {
                        direction: "ScrollUp";
                        threshold: 1;
                        mode: "OnInterval";
                        interval: 1;
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_LEFTCTRL", "KEY_LEFTSHIFT", "KEY_EQUAL"];
                        }
                    },
                    {
                        direction: "None";
                        mode: "OnRelease";
                        action =
                        {
                            type: "Keypress";
                            keys: ["KEY_LEFTCTRL", "KEY_F10"];
                        }
                    }
                );
            };
        }

This gestures group has the same problem with scroll wheel actions (works on M720, but not on MX Master 3), but the rest can be used (vertical movement switches windows, horizontal movement switches tabs, single click shows all windows to switch).

You will need to merge the following branches:

Those branches are from pull requests:

UPD:
I forgot to set parameter target: true for MX Master 3 in logid.cfg:

    hiresscroll:
    {
        hires:  false;
        invert: false;
        target: true;
    }

With target: true scroll mappings works fine on MX Master 3.

I experienced slow/weird/buggy scrolling after updating to 22.04 from a pretty old version of Ubuntu/GNOME Shell, so I updated the gist.

Notes for what I did:

• sudoedit /etc/logid.cfg
• set hires: true
• sudo systemctl restart logid to use the changes

Scrolling was fine after.
