Want to double-down on this. I read "native" and immediately assumed the main selling point was perf - which enticed me to open the link.
Slack in particular is extremely, extremely slow, even by Electron standards. I can't expand it to the full-height of a 4K (running at 1080p) portrait monitor without typing becoming unbearably laggy, so I either have to keep it at 1/3 monitor height, or have to use another application for writing the text.
- accessibility built in which benefits everyone
- native application scripting
- consistent keyboard shortcuts, including focus ring movement
- ability to App Nap / fast system shutdown
- consistent retina/DPI behavior across display drags
I've been developing Mac native software for 20 years now and I'm still wowed by some of the things that come with the toolkit for free.
