Very new to Welkin suite - just installed it. First thing I did was to open up an apex .cls file to take a look at some code. NO SYNTAX COLOR CODING? What?
Is this a bug? is this something you need to enabled?
also: this file is not part of a project/solution, it's just a single .cls file - wouldn't think that would make a difference
after a little more research - looks like your product does not syntax color code based on the file extension alone - seems like the file has to be in a project to get syntax coloring. Not sure if this is a bug or not - wierd.
after more research - look like only .cls files (when not opened from a project) are not color coded. Other files are syntax colored ok: .js .html .css
