I have some folder ~/foo which I'd like to protect from accidental deletion, that is I'd like to protect it from deleting with rm -r ~/foo or rmdir ~/foo.
I realized you can do that using chmod a-w ~/foo or chattr -i ~/foo but this has the drawback that you cannot change anything inside that folder. I however would still like to be able to create/move/delete files and folders inside ~/foo.
Is it somehow possible to do so?
When Gnome Files (nautilus) is in list view I sometimes still want to open the right-click menu that otherwise appears when you right-click into the empty space of a folder. (The one that lets you open the terminal etc.) Is that somehow possible?

To edit the categories in the thunderbird lightning calendar could go to Tools -> Options -> Lightning -> Categories, but in the current version (60.3) this doesn't seem to be possible anymore as Tools -> Options was removed. I also couldn't find it under the Preferences.
How is it currently possible to edit the calendar categories (delete, change color etc)?
I have the vanilla Ubuntu 18 installed on a computer and I'd like to completely disable the lockscreen. But even after disabling it in the settings (see image) it still shows up after "waking" up from the screensaver (blak screen), you just don't have to enter the password anymore. Is there a way to actually completely disable it such that it also doesn't show up after coming back from the screensaver (I'd like to keep the blank screen as screensaver)?
For a few days now I get following pop up whenever I start the computer and sometimes randomly during the session:
The censored part contains my e-mail address. How can I find out which application this is?
When you manually install programs and you want to add them to the "Open With" list in the context menu, you usually have to create edit multiple .desktop files I think is rather cumbersome as there are a lot of ways to make mistakes. Is there a a program with a GUI to do that for you? (Or maybe even a native way?)
I have found alacarte but that only makes your programs available for adding to the launcher.
