modular snippets

[kqvanity]

First, I'd like to thank you for your effort on this project. However there're few areas that I find worth enhancing.

• The ability search through snippets themselves.
• Easily create new folder. Already mentioned in this issue.
• Having separate kind of boxes on the right-hand side for the code snippets, which can be searched/referenced via their comment, or generally cycled through (Rather than a pager for an entire file).

That was initially raised as an issue, before migrating it to a discussion instead.
