English is slightly ambiguous here. As tighten has 2 meanings. Turning a screw clockwise is to tighten it, as opposed to loosen it anticlockwise. But it's quite loose. Finally, to make it tight and secure, you tighten it with one last turn.

In KDE Plasma, if you right click on the launch menu button, there is an option Show Alternatives. Here, you can immediately select and use one of the installed alternative start menus. On top of that, you can install further launcher menus, which will then appear in the Show Alternatives list. I installed Simple Menu (from Eike Hein) that has categories, favourites and search. And let's you move the icons around. But its that easy to try out different launchers. I hope you find a good one.

Not being fast at typing does not mean you are not tech savvy. There is more to tech than typing. Like an architect doesn't need to be good at brick-laying to be a good architect.

Twitter was a cess pit before Musk took over. It had gone the way of most centralised networks. People won't leave or they get cut off and lose their followers. Networks know this, and stop caring. Twitter still exists because selfish people won't leave. Never join any centralised network. You are helping it go bad. Musk did a good thing in chasing millions off of Twitter. Some stay on there and grizzle about the mess, they themselves, made, and blame it all on Musk.

For using osm as a map, it's great and very detailed. For cycling navigation it's ideal. And beats Google maps that fails to find a route without a data connection. Like when roaming. And in many poorer countries, where humanitarian agencies desperately need maps, Google doesn't bother to map any details, because there is no money in it for them. Fail again.

And, as with railways, companies love to build new, as you get a monopoly. But maintenance? No financial benefit to doing that.

For simple screen recording, I could only find not-so-simple OBS that let me record a part of a screen. In the end it's a good and reliable solution once you set up and save the local area I want to record. Not so spontaneous, but solid.

I edit the videos in KDEnlive Windows install, which is excellent for this work. I have a smooth process and create many videos quickly.

Mount a network share permanently on Kubuntu. Non IT people need to do backups too. And Plasma apps can't access network shares unless they are mounted.

Yes. I've been using Linux for over 10 years without touching the command line. I used Ubuntu up to Unity, then switched to Kubuntu and Plasma. I'm not in IT, so I don't need IT stuff. It all works by GUI. People who haven't tried it might say it's not possible. But they are not speaking from experience. Some others, not interested usability, don't understand why GUIs are so successful and dominant. Which is absolutely fine, as long as they don't try think they are suddenly knowledgeable in usability, and have tried 10+ years of GUI only.

For many people it's not quicker or easier. If they've not used CLI before, they'd need to learn multiple new things. Going to a Web browser for help every time, before doing something is not quick. Memorising precise command strings that mean nothing to the user, is not easy for many either. For them it's bad usability.

Directory means a listing. You are referring to the list of names of some items.

I'm usually working with folders that actually contain files and other folders. It's often closed, so the content is not shown. A folder is a container.

Wikipedia clarifies this difference.

A telephone directory does not contain telephones.

We're not allowed to call part of the night sky, the Milky Way any more.

Oh hell. I've been drinking Scheuermilch! I thought it was a bit crunchy
