Menu has both "Discord" and "Discord (Env)". Why 2 versions, and how do I remove the latter?

I downloaded Discord from (chose a .deb file), and installing ended up giving me both "Discord" and "Discord (Env)". Is there a way to get rid of "Discord (Env)"? Snap (which I suppose installs Discord when the .deb is double clicked) only shows 1 "discord".

I have an old Ubuntu machine that no longer works, but I can still access its drive through a live USB. None of the notes were ever exported; though, I was expecting to recover them by some other means. How do I do this?

What is the effect of packages installed by snap on memory usage?
us flag

I never used snaps before. When reading the vague descriptions I assume it's implemented in a way really similar to containers.

This makes me assume that programs in snaps all use their own libraries. But because 'regular' programs use the default libs from the system I assume multiple libs will be loaded which will cost a lot of memory...

Is this indeed the case ?

Add mounts/symlinks into snap automatically
cn flag

I use several symlinks in my root directory usually pointing somewhere into /home directory. I can keep projects organized in directories, but I still have quick (terminal) access to them.

e.g.: /g -> /home/z/projects/kotlin/TheGame

But for snap applications, these symlinks are not visible.

Does exist any way how to globally add such symlinks (/bind mounts/another solution) to snap applications?
