+1. Sublime is a fantastic lightweight text editor, but the version that I've used simply isn't an IDE. Excited to see what new features are in this one, though!
If you just want something lightweight to open text files but still have some basic syntax highlighting, there are heaps of choices that are better Mac apps. I'd suggest any/all of these three (all of which happen to be OSS but that's not why I recommend them - I didn't actually realise until now that they all are)
- SubEthaEdit: https://subethaedit.net
- CotEditor: https://coteditor.com
- TextMate: https://macromates.com
(by the way, completely random question: do you happen to know a lightweight image editor on osx? I tried few and they were either not working, bad, or some combination of both; on windows I use Paint.NET which does all I need and is fast, quick to start, etc..)
They also don't reduce everything to a literal screen of text (seriously, I hit Cmd-, in Sublime to see preferences, and just got an empty text screen... I guess I have to just work out what options it has by randomly trying stuff?).
The extent of my image editing needs on macOS is typically solved by either the "Markup" tool on an image, or Preview (i.e. highlighting/drawing attention to something on a image, and/or cropping an image).
