Does ST support icons in the completion panel? I have not seen them before and I wanted to implement them for a Language Server (LSP supports this but ST may not implement them). If not can I make a formal feature request?
It’s not currently possible to add icons in the autocomplete panel, but depending on your needs you may be able to approximate it by using unicode characters in the completion hint. I haven’t tried it, but if that works I don’t think you can specify alternate colors for them.
You can add a feature request in the issue tracker (if there isn’t already one there).
It was also hinted by the devs on the Discord last week that the next dev cycle will include some changes to autocomplete, so possibly this is already in the works (but that is just a guess).
Thanks, I added a request https://github.com/SublimeTextIssues/Core/issues/3009.
