anyone aware of a quick switcher like this but for open windows/tabs on Mac? AltTab which seems to be the popular options doesn't seem to have a quick switch/fuzzy finder.
This is off-topic because this thing is about cmd-tab switching instead of typing a couple keys to switch to a particular window, but I just wanted to second the mention for hammerspoon as a "can probably solve your issues with macOS interface" multitool. Since you write in lua (or anything that compiles to lua, like fennel) it's incredibly easy to iterate on.
By Finder do you mean Spotlight? My gripe with Spotlight is the instability of the pre-selected item after you type a few characters.
On my mac, if I'm trying to go to Finder, I get
cmd+space (Spotlight Search)
f F(inder.app)
i Fi(nd My.app)
n Fin(d My.app)
d Find( My.app)
e Finde(r.app)
so quite often I'll see Finder.app show up as the result, but I've already told my fingers to type the 'ind', so there's a race between "type these keys", "see Finder", "type return", and "see Find My".
It’s not a coincidence that this is happened and I’m sure the government has been well aware—they just make too much money from it to care to slow it down.
