UI/UX suggestions & improvements

[NA0341]

Basic functionality to add:

• add HEX color text field for user color (this is actually an Etherpad issue)
• add »select all« checkbox in selection mode

UI Behaviour:

• ~~open~~ share pad entry directly by swiping right
• select pad entry by swiping left
• sort pads (edited, accessed, name | ascending, descending)
• night mode (follow system theme | Material You)
• move »edit, share & delete« as buttons to the toolbar in selection mode
• long press on the group button adds all lines in the clipboard as groups (confirmation if more than 8 lines)

Option schemes for additional options:

• Add from clipboard (long press on »new pad« button adds a pad link from clipboard to the list and automatically detects if it's a generic or specific link; if the link is generic, an input field for the name spawns)
  • open the pad directly
  • add all pad links found in the clipboard
