I saw this on Delphi Praxis, which motivated this feature suggestion:

On Mac, I have used SnippetsLab for Delphi code snippets. I have exported them to a json file.

Does anybody know a good snippet manager for Windows that:

• supports Delphi syntax
• can import json files
• has good organizational features like tags, folders, search, filters, etc.

with reply:

Good is a relative term.. 😉

GExperts has a 'Code Librarian'. https://blog.dummzeuch.de/experimental-gexperts-version/

Then there is CodeSnip. https://github.com/delphidabbler/codesnip

I use both.

Neither have all three of the capabilities you mention.
