Recently I've understand that for my happy Java-codding life I need some improvements for content assist. So I'm trying to figure out how can I replace Content Assist tool tip popup in standard Java Editor with custom window.
I'm completely new to eclipse plugin development so I have a few questions.
Is it possible to do with plug-in without creating custom editor? I can't find valid extension point for this task am I missed something?

I thought CompletionProposalComputer only allows to add new content to the existing content assist window. My idea is to make more advanced completion proposal window with 2 or 3 proposal lists depending on execution content.

I'm not sure what's wrong with that, but if you want to replace the wealth of existing proposals with only your own, please see that the preferences allow to individually disable each category of proposals.

If you are saying you want a different UI, yes, then you need to implement something entirely new. (You're certainly aware that execution content is of course taken into consideration by current proposals).

You may also take a look at Code Recommenders, to find out to what degree completion can be modified, refined etc.
