[FEATURE] Add customizable variables to snippets

[Silver0006]

Suggestion

Would it be possible to add customizable variables to snippets? I use ByteStash to store presets. For example,
7z a -t7z blank.7z -mx=9 -m0=lzma2 -ms=on -md=512m blank.txt

So instead of using blank.7z, you could write {output_file}.7z and then define {output_file}.

Solutions

1. Variables would be visible on the snippet so you could type them before copying.
2. When you click copy on a snippet with variables, a popup will appear and allow you to type them in.

Extra

• Maybe add the ability to create presets for the variables with a drop down menu.
