Mercurial Support was added as part of IDEA 10. Is that support coming from just bundling the hg4idea-luciad plugin with IDEA 10 or is there some other support provided?
If that is the only support IDEA 10 has, I would really like to see that functionality enhanced to bring it more on par with Git and SVN support. In particular I'd love to see the incoming changes and history view (with graph! <g>). I'd like to be able to see the history of an individual file. I'd also like to have better visibiltiy to the repository (branches, heads, easy way to get the delta between them, etc).
Although the current support is very helpful, I still find myself needing to switch to TortoiseHg and the cmd-line frequently to get a better idea of what's going on. (Something I never needed to do with SVN for example).
