I think you should offlineimap; Use mbsync ( iSync )

Offlineimap and mbsync are two separate tools that do the same thing. I've had a good experience with offlineimap. In both cases, however, the hard part is not picking the tool but configuring it.

Go for Emacs.

It is niche, belongs to the oldest softwares, and a true mark of professionalism:)

And make sure you use tabs!

Heresy! Always indent using spaces so that you can easily use Vim's `conceal` feature to replace the spaces with the 🅱️ emoji. /s

Just one : Emacs orgmode

Yes I think serious practice is needed. There is something else that is a disadvantage: you need anyway to review your lecture notes; but since they are so beautiful you do not easily see mistakes; one way to avoid overly beautiful notes is to use a kind of draft font that deliberately looks a bit off. The drawings (with the keyholes ) are of path integrals with holomorphic functions (something I did around 1982)

But the whole idea and execution are phenomenal.

My feeling is that using emacs it could be possibly easier but I will not try to convert a vimmer

And add some crushed nuts like almonds
