Other Code Tools

Some people are aware that I keep a development branch of the RB in the Open Repository under the branch numbering scheme of "4xx". One of the things we hit when trying to provide some better tabs for the code tools at the bottom, is that we needed to redo the architecture that tabs use to register themselves. I'm much happier with the new scheme, it seems to be more failsafe. But it's not really backwards  compatible. Simple tools are easy to convert. So much so, that it detects the use of the old API and offers to rewrite the code to use the new API. I'd like to sweep through all of the publically contributed tools and see which ones have issues. I know that the RBDefintionTool does, as do SUnitToo(ls) and RBSUnitExtensions. I have been back burner tinkering on an entirely different way of doing SUnitToo(ls). I'd imagine we'll do a like version for RBSUnitExtensions or help someone who wants to maintain it do so. The new browser actually has a built in tab that is meant to eventually replace  the DefinitionTool tab, so I'm not too worried about it. I know that RBStoreExtensions works, as does RBRegex thing, and the RBByteCodeTool. So what other tools are in popular use and in high demand?
