Thanks for the detailed answer. I'll give it a look.

I also like the idea of installing software "as intended by their developers" and I don't like Linux distros that make a lot of changes and customizations. That's why I like Slackware for example, a distro that remains "pure" and intervenes as little as possible. Good idea!

Interesting options if you’re into self-hosting (I’m not atm)

I do use it for tracking studying time or cycling.

I don't know about local send specifically, but KDE Connect will do that. And if you have an FTP client on your phone, then yes you can easily spin up an FTP server on your local network and transfer files that way

Google Slides Free and quite convenient. Works in the browser and has mobile apps. However, this is a cloud service, so if you need a completely offline experience, it will not work. OnlyOffice Presentation The free part of OnlyOffice includes a presentation editor. Can be used offline in a mobile app or desktop. The interface is more modern and convenient than Impress. Partially FOSS (client is open), you can disable the cloud. Calligra Stage Part of Calligra Suite is a free office suite with a presentation editor. There are versions for Linux, Windows, but there are no official mobile clients. The interface may seem unusual, but the functionality is decent. WPS Office (free version) Free office with presentation support. The interface is similar to MS Office, convenient and modern. Not fully FOSS, but free and works offline. Deckset (for macOS, paid) A very convenient tool for creating presentations based on Markdown. There is no free alternative on Android, but this is an example of the approach. Marp Markdown-based presentations. Free, cross-platform (there is an Electron version). It requires a little getting used to Markdown, but it is very flexible and convenient for those who like the text approach.

LibreOffice Viewer — The official LibreOffice viewer, available for Android. True, it mostly only has viewing and very basic editing. But it's native and offline. OnlyOffice (standalone version is optional) — There's an Android app that can be used offline, with support for major formats (DOCX, XLSX, PPTX). Although the software is not fully FOSS, the client is open, the server can be stored. Collabora works better on mobile devices. OpenDocument Reader/Editor — Less well known, but a simple ODT rider and editor, you can search for it in F-Droid. Very lightweight and offline. AndrOpen Office — A port of Apache OpenOffice to Android, fully offline and FOSS. The interface is old-fashioned, but the functionality is decent.

Gadgetbridge in just about the only one. The problem is that the watches themselves use proprietary BS Bluetooth protocols with their own cryptic values to stop people from decoding their own devices unless you use their app...

I unfortunately don't have any experience with video in Publii. Hopefully this would be an easy to add feature at some point.

the logic that sending messages alters political reality is part of the overall problem. Politics is a conflict of forces, not a conflict of ideas or opinions. A license is as powerful as the will of the state power behind it to enforce it. Otherwise, it is powerless. If you want to make sense of the political world, I invite to move beyond the idea of "taking stances" or expressing positions as a political act, and reason instead of what incentives and powers you're altering with your political actions. What you describe just does not play out in real life: neither on a micro scale nor on a macro scale.

Vim has that same kind of tutorial, that you can access right within the application. Such a nice feature. I didn't know that about Inkscape, now I really want to try that one.

There are different communities for answers like that, for general techsupport. Maybe OP asked it in a wrong place, but if it's already here, and does not sound blatantly oftopic it should be answered in the spirit of the community. And the answer was also wrong, OP asked how to save as inverted, not how to open inverted.

Instead of Firefox we need hundreds of stripped down browsers some first year CS students cobbled together in their basement for browsing the web. Or something like that, I didn't quite follow either.
