[Feature request] Add text manipulation functions - sort, shuffle, transform, etc.

[tur1ngb0x]

Is your feature request related to a problem? Please describe.

I frequently use text manipulation operations when using text editors to type my code and notes. Notepads app does not currently support any manipulations such as sorting, transforming etc.

Describe the solution you'd like

I would like to perform operations on the entire document or on the currently selected text such as:

• sorting - alphabetical, numerical, case, natural, length, ascending, descending, shuffle, unique, etc.
• transforming - uppercase, lowercase, snakecase, titlecase, etc

Describe alternatives you've considered

Other text editors such as Visual Studio Code, Sublime Text, Notepad Plus Plus have similar features.
