On a file share, a notes directory with each category as a subdirectory, and plain text files for each note. Accessible from my computers and phone.
On my laptop, the launcher for my text editor (Pluma) points to a bash script that creates a blank text file YYYYMMDD_text in ~/.drafts and opens that file with Pluma. If it already exists, YYYYMMDD_text_1, or whatever increment is created. That’s mostly to take advantage of Pluma’s autosave feature, which only works with already saved documents. Then I save the document to the file share if it’s worth keeping.
To make it clear, I would still use Linux with GNOME/libadwaita over Windows any day. Yes, some themes are ridiculous and will be a nightmare for any developer to work around. That said, I can’t help but be concerned about the coming demise of theming with the way GTK is going.
What first pushed me to start exploring Linux was when Windows 8 forced the Metro theme down our throats. My time with Linux would have started three years later if M$ had kept Windows 7 theming options - that’s how important a customizable, sensible theme is to me.
I’m glad that I don’t have to do that again since there are DE options that do insist on keeping theming alive.
