I use Keep for checklists and disposable notes, and Joplin (similar to Obsidian, but open source) for my “forever” notes. I look for apps that give you the option of exporting notes in a common format (currently markdown), and I have notes that have followed me through several changes of note taking programs.

You’re already using Obsidian, so my suggestion is… Take notes! Take notes on cool software you’ve discovered, take notes on your settings and configurations, take notes on any issues and bugs you’ve had to fix, take notes on how to use unfamiliar programs, take notes on Linux terminology. You have a huge personal knowledge base from years of using Windows. Linux is not hard to use, but it takes time to become second nature to you.

A qualified yes. I love the overview, which is, IMO, the most elegant way to launch applications and manage workspaces of any OS or DE. I also love the general look and fluidity of the environment and how it gets out out of your way when you don’t need it. But I preferred the pre-GNOME 40 vertical workflow to the new horizontal workflow.

There are also three must-have extensions that make GNOME usable for me:

• AppIndicator and KStatusNotifierItem Support. GNOME can wish away tray icons if they want to, but the tray hasn’t gone away and is still necessary for some applications.
• DashToDock. Makes app switching more accessible and adds right-click to close.
• Gnome 4x UI Improvements. Increases the size of the workspace thumbnails so you can actually see what’s in them (like it was before GNOME 40).
