Firstly - many thanks for Joplin! It's a life-saver, especially after leaving the slow and bug-ridden Evernote.
Just a minor suggestion. In most applications the shortcut CTRL-P is for print. Currently in Joplin this brings up to 'Go to' dialogue. I'd suggest tweaking the default keyboard shortcuts to be slightly more familiar:
Thanks again.
Ctrl + P is a common shortcut in many applications (especially text editors) now for a fuzzy-finder or goto dialog so people may well complain about the reverse.
@uiop-on welcome to the forum.
I too have been "conditioned" to using CTRL+P for printing 
.
I just used the keyboard shortcut editor (Tools > Options > Keyboard Shortcuts) to change the shortcut keys. Basically Joplin lets you "tweak them" yourself...
EDIT:
If you make lots of changes to your shortcuts you might like to know that they are stored in keymap-desktop.json in your Joplin profile folder. Also the "Simple Backup Plugin" does back this file up along with all your other Joplin data.
