What's a unique customization on your Linux machine you think no one else has?
Just wondering since I know a lot of people quietly use a screen-area-select -> tesseract OCR -> clipboard shortcut.
I separate subjects of interest into different Firefox windows, in different workspaces -- so I have an extension title them and a startup script parse text to ask the compositor to put them in the correct workspace (lets me restart more conveniently).
I have automatically-set different-orientation wallpapers for using my 2-in-1 depending on whether I use it in portrait or landscape (kind of just for looks, but I don't think if anyone else adds a wallpaper change to their screen rotation keybind).
I'm pretty sure no one else has my shell script that takes a picture, uses imagemagick to copy a scaled down version of it to a special folder, and then build a string that allows me to just middle click paste the image into Rednotebook so it appears correctly.
I used to do my daily journal as plaintext in Vim. I wanted something that was a little more capable and in RedNotebook I almost got it. It stores plaintext markup (I think yaml?), the thing is it has an edit and a display mode, and you can't edit it in display mode. Inserting a picture is pasting a file path to where that picture is stored. If I linked to where the pictures are stored in my ~/Pictures directory, if I ever migrated from Rednotebook or Linux or anything like that, the links to those pictures would break. So I store teh pictures I link in my journal in a subdirectory alongside the journal itself, so the pics should go with it and it should survive a transfer easier.
This is, of course, extremely user unfriendly to do, because it would mean copying pictures, reducing their resolution so they don't take up the entire damn journal window, and then working through RedNotebook's interface to navigate to where I just stored that picture to generate the link.
Or, I wrote a couple lines of Bash that did most of that for me and put the file path link in the primary buffer so I could open my file browser, right click, select Add To Journal, and then middle click in my journal. Felt kind of clever coming up with that one, and I kind of wish A) it was a bit easier and B) we lived more in a world where we did that kind of thing where things interoperated more than trying to silo things.
