Hrm good point, any higher level API we can tunnel that through?

Dunno, they're adding all sorts of fancy things. Devmo might have something. I think they recommend that you use an unimplemented API, or something silly like that.... 😞

Damn for a second there I thought Devmo was some fancy new API.

value: "\n{\n [[%tabstop:]]\n}": as you can see - space instead of tab. I think value: "\n{\n\t[[%tabstop:]]\n}" is more logical.

It's not meant to put a tab, ko.projects.snippetInsert will take care of that as per your preferences.

Note to those who prefer 1TBS curlies, use the following:
value: " {\n [[%tabstop:]]\n}"
