Why?
At some point, they will need to introduce some kind of subscription for some of their browser features - I assume that current Arc Max is going to be part of it. This would lead to making new features available only to the paying users.
I have really pessimistic views on software development (for-profit or not) in general now, so I'd be really happy to be wrong here.
Obsidian - note taking, making presentations for work-related stuff.
iTerm 2 - it's better than default terminal emulator, but i consider moving to Alacritty to see what's so hype about it.
Scroll Reverser - macOS still doesn't know the difference between mouse scrolling and trackpad scrolling.
While i can't recommend Arc browser, i still use it daily. I don't believe it will exist in it's current form in two years, but now it's much more usable than other Chromium-based browsers for me.
I also have a simple shortcut in Siri Shortcuts that calls m1ddc tool to change the external monitor current input between HDMI and DisplayPort.
It was one of my first realtime collaborative experiences in the internet and it was magical at the time, i still believe that services like Miro grew out of World of Text.
Edit: couldn't find the forum post but found the tweet, wow, it was more than a decade ago https://twitter.com/anVlad11/status/23055592331 . Were old pages wiped?
