I don’t know of any. I do like keyboard based workflows so I have VimiumC in firefox which does what you want. A tiling window manager is the solution for the desktop environment part. The tricky part is navigating existing GUI apps.

They all work using macOS’ accessibility API which exposes UI elements for programmatic interaction.

Because linux doesn’t have a unified framework because of our freedom, things like this are very tricky if not practically infeasible (at least as far as I know).

edit: There was also a thing where you divide up the screen recursively with keyboard shortcuts and when the intersection hovered over whatever you want to click you could hit a key and it would generate a mouseclick there. I forgot the name, never tried it either. But a plus is that it doesn’t need applications to implement a certain API to work so it would work system wide.

I have been watching Sayonara Zetsubou sensei lately. Also Pani Poni Dash! is an interesting watch.

• Hidamari Sketch
• Lucky Star
• Non Non Biyori
• Yokohama Kaidashi Kikou
• Gochuumon wa Usagi desuka?
• Tanaka kun wa Itsumo Kedaruge

Hidamari Sketch is very underrated and is much less well known than it’s contemporaries like Lucky Star, but it’s basically the comfiest thing ever. Any CGDCT/SOL could work for this (Nichijou, Yuyushiki, Kiniro Mozaiku, K-ON!, …) but I specifically chose shows with a slower tempo.

very glad indeed

What is similar? Does it need to be a band anime? Does it require social anxiety characters? Just cute girls doing cute things (CGDCT) in general? Have yuri elements?

• slice of life (SOL) with characters playing in a band: K-ON! (band aspect is secondary)
• SOL with anxious main character: Hitori Bocchi no Marumaru Seikatsu
• general SOL/CGDCT classics: Lucky Star, Nichijou, Azumanga Daioh
• more modern SOL/CGDCT: Kiniro Mosaic, Gochuumon wa Usagi desuka?
• SOL with yuri: Hidamari Sketch (moderate, also a classic), Yuyushiki (lots)

edit: I personally don’t think that Bocchi the Rock! is super laid back, but if you compare it to action shows it obviously is. If you really want to go the laid back route you can look into the genre Iyashikei (“healing type”) with anime such as Non Non Biyori, Yuru Camp (still have to watch this one so can’t verify personally but is very popular) and Yokohama Kaidaishi Kikou (absolute classic).

I love that he has only 3 colours and that green is not next to yellow.
