As an eight year user of IDEA, I love it to bits of course, and take for granted its code completion actions.
I have need of a plugin that once actioned will continually update a particular block. It would watch for changes to particular method signatures, and rewrite code elsewhere in a source file accordingly.
Most code-completion plugins, or light-bulb driven invocations of plugins from the editor are once-off actions. Are there any that will continually work that I can be inspired by ?
