Why exactly did my @CoMaps forget all my gigabytes of recently downloaded maps one second before a trip across Germany now that I have terrible mobile internet?

It's inexplicable to me why apps for #Immich and #Paperless do not have a *button* to upload files from the filesystem. You must use the share-to mechanism from *another* app 🤪 So instead, I just use the webinterfaces (which do have sich a button!), those also have much more features anyway...

I'm moving back to #tmux. #zellij is too weird. Too much fiddling with theming (tmux doesn't need theming to make it readable), zellij messes up emojis (tmux just does it correctly), and overall I just tried too hard to make zellij behave exactly as my tmux setup. So why not just stay on tmux.

I do like that #SolveSpace can load images (though only pngs...) for reference to design your model around. But I really wish it was a *little* easier to auto-scale it to its real dimensions 😅
