While I disagree with you, this made me chuckle. A great joke. Wish you all the best.

(Also what’s HTH?)

“Happy to help.” or “Hope it helps.”

I especially appreciate that the graph is designed as “Linux” and “Other” instead of “Windows”, maybe “MacOS” and “Other”.

You are mistaking KMail (desktop client by KDE) and K-9 Mail (Android client that is being rebranded into Thunderbird for Android).

GitUI is amazing. The only caveat to many developers is that GitUI is still unusable when you GPG sign your commits, even after so many years and with functioning PRs already created. This excludes, in my opinion, a large portion of the possible users from using GitUI. However, it might still be useful for everything Git-related which does not require creating/changing commits.

That is example that looking for new apps part I mentioned. I know there are FOSS Android video and proto editors. I just never needed any of them, so I don’t know which one is better or worse, but I know there are a few I have heard about in recent years. I know I have seen several contacts and dialler apps on F-Droid. Time to check them out one by one and hopefully one will fit the needs with minimal concessions. Others in this post have already mentioned some apps. See if they might work for you, too. I wish you best of luck looking for the right apps for you.

I think it is worth mentioning that there is an alternative for each one of Simple Mobile Tools apps. It will just mean we have to spend some time looking for such apps yet again. We as users of FOSS software must be always prepared to move from one application to another. This is why walled gardens, export to / import from open standard formats and in general easy replaceability of FOSS SW is important. This is just a sad fact about using FOSS where FOSS maintainers are just normal people, with all their needs, faults, and weaknesses.

Welcome. Sure, Linux Mint’s WebApp Manager or Peppermint OS’s Ice are here for you. But jokes aside, sadly, no. Lemmy does not have a native Linux application as of now. But you can make use of the fact that the browser UI is a PWA which can be installed like a regular app as well.
