#new linux user

Hello lovely Linux (Mint) understanders in my computer idrk what this shit is or which bit I need to modify. When partitioning the drive at install I didn't touch anything I just went w what came up. Previously I was using Windows 10. I partitioned to keep all the documents etc on my hard drive (as a just in case. It's all on a USB as well but I couldn't quite bring myself to wipe it clean), so ig that's all sitting on the partitioned bit (along w all the microsoft/windows bloat ig?)one

I downloaded GParted bc I saw someone on the Mint forums suggested it but idk which bits I need to move or how much

Is there a good Linux alternative for WordPad (SPECIFICALLY wordpad. Not notepad, and I already have libreoffice, but that's a word alternative. I use WordPad for writing bc word/writer is too much and notepad is too little- it's a nice balance of extremely basic w a little bit of formatting ability)

Is there a way of enabling single-finger touchscreen gestures on Firefox (swipe to scroll, pinch to zoom etc. atm all any touchscreen gestures do is highlight text)
