That's why I've been using Atom instead. Since 1.17 or so it got quite usable and it's getting better with every iteration. Nowhere near as fast as Sublime Text but usable for daily coding. I disabled the git plugin because we're using fossil. I hope it doesn't become an IDE like VS Code. At least they made the IDE packages separate.
Regarding fossil, do you use fossil for tickets and self-hosting? How well do fossil tickets work compared to Github issues? Do you use any custom themes for fossil tickets?
We used tickets somewhat and we are self hosting through a nginx proxy in order to log the http activity and proxy over https. The ticketing has markdown support. We use a custom theme, not for tickets but for the whole repo. Fossil tickets are only used internally, we use osticket regular ticketing.
There is also a service for hosting fossil repos called Chisel, but it's nowhere near as useful as Github.
