VIM is my favourite text editor. It is very powerful and highly configurable. It took a lot of time to me to pass from 'what am I doing here?' state to 'omg, I've got a power!' state.
In order to have more power in VIM I write plugins for it from time to time. If you you like them, use them at your own risk.
Tagmaster allows you to easily operate with tags and tag files. Using a couple of commands it allows you to generate tags, delete tags for current file, update tags for current file, and so on.
