What non-FOSS software are you using that you wish you could replace?
For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn't have to be work related, thats just the thorn in my side right now.
Onenote! I use it for school and work, and love the syncing capability and the flexibility in structuring and organizing my notes. I also like the keyboard shortcuts and the way it can dock to a side of the screen to keep the main content visible
Would https://anytype.io/ be a replacement? It's very new so you might not have heard of it. It's designed like Notion, but it might have everything you need.
Other FOSS options are Joplin and Logseq. I'm an Obsidian user myself; not FOSS but the storage format is completely open which is the most important to me.
I adore obsidian, but would love to see an open source software that is on the same level. The extensibility and keyboard-shortcut driven nature of Obsidian makes it a dream to use!
