Spotlight was bad back in the day, so I installed Alfred and started using that. Then Spotlight suddenly improved a lot, enough that it was usable for me, and I deleted Alfred. Then about five years ago something happened internally at Apple to the Spotlight team and it just got worse and worse and more difficult to use, making me regret deleting Alfred.
I wish Apple would just fix Spotlight. They don't seem to think it's worth fixing.
That is a good question. I like my dock uncluttered. I have it placed vertically on the left side, with only the apps I use every single day: Alacritty, Brave, Cursor, and Zoom. With Finder and Launchpad included, that's only six docked apps. Everything else I use Spotlight to open, so I feel the pain when the usability gets degraded or buggy.
