Add possibility to create by user custom toolbar with actions defined by user Something like in atom:https://atom.io/packages/tool-barhttps://atom.io/packages/flex-tool-bar
You can have something like this: https://github.com/titoBouzout/Toolbar
Other than that, I don't see this coming any time soon if at all.
Doesn't work on newest ST @tito ?
--- Edit ---Doesn't work on Mac, on Win works OK....
Atom & LightTable are doing some pretty innovative stuff relating to customizable UI ( and otherwise ). It would be great to see ST make some progress in that direction.
