Whoa, I had no idea! I knew about alt+shift+F4 to open a terminal in the current folder, but that spawns a whole separate konsole instance, F4 is amazing, thank you!

Motherfucking pockets.. in the goddamned shower curtain.

What good does that anger do you? It's not going to change them, all it's doing is eating at you. Learn to set it aside, to have some compassion and understanding for your fellow humans even if they don't 'deserve it', and you will be much happier in life.
How does the dolphin/konsole integration thing work? I'm curious.
UpNote. I use it like a combination of the gollum wiki described by OP, but I just put everything in there. I have watch and reading lists for things I want to check out, writing projects, notes for TTRPG games, I keep extensive notes on healthcare-related stuff, and so on. I like UpNote because it's lightweight, has windows, linux, and android apps, and because it has a one-time $25 lifetime membership that does free syncing forever instead of a monthly subscription like most other things seem to. I've tried OneNote, Evernote, Obsidian, Joplin, AnyType, and a bunch of others and didn't like them for various reasons, but UpNote is both pretty small and also has a pretty full-featured editor that can do rich text, all kinds of formatting, media files, etc.
The only thing I've run into that UpNote wasn't ideal for is I started writing a novel a couple months ago and managing the structure and notes and all that got a little unwieldy so I picked up Scrivener. Still wish they had an updated linux client or there was some good, complete, feature-rich linux-native equivalent, but it runs pretty good under wine, so.
Oh damn, I hadn't thought about this but that's not a bad idea. My mom used to have one when I was a teenager and would make this potato bread that I friggin' loved. She always said it was dead simple, maybe it's time to look into that myself.
Wait, I've been on this earth for 52 years and somehow didn't know they make shower curtains with fucking pockets?! I'm going to go buy one right now.
It's like anything else, it will take time to get comfortable with it. During that period you should probably focus on getting practice in out-of-the-way places where you're less likely to be overwhelmed or distracted and can potentially cause problems. As someone who has never been able to drive and lives in country whose general opinion of public transportation is 'Hahaha no', not being able to drive can suck pretty bad. I'm always relying on others, beholden to their schedules, their bad planning, their poor time-management skills, etc, and the only alternative is taking a cab which gets expensive quick. Being able to drive, even if you don't do it a lot, is a valuable skill and something you will get more comfortable with the more you do (and doing it regularly is key to build that familiarity and level of confidence.)
I haven't had the app installed since I got my phone. I don't believe it was installed by default, or if it was I removed it immediately.
I'm 52, I remember when websites were little more than 'Oh I guess we have to have an internet presence, so here's a website that's nothing more than an ad for our TV show, book, movie, etc.'
Maybe? shrug I didn't look too hard, I stumbled across someone talking about dark reader and was like 'I must have this in my life.'
Shorts are the only thing that really annoyed me, I don't mind recommendations or comments, and I just keep a tab open on my subs page all the time anyway.
