Currently, on android at least, in a screen with a list of notes (/to-dos) (notebook, tag, search screens) you have the following actions available: move, copy, delete. In a screen viewing an individual note you have a menu button, with several other actions. But most of these can logically be applied to multiple notes: applying a tag to multiple notes, concatenating the markdown links, concatenating properties-reports of multiple notes, etc.
So my question is, why not merge the menus, and make those actions accessible from list views? They would be applied to the selected notes in the list.
I find myself quickly sharing URLs from the mobile browser to Joplin, then I want to link to the notes created from each url in a more general note, and I need to enter each one to create the markdown link, paste it, and go again.
