So I had to manually apply a CVS tag to some files in my project today and after selecting the files in the Project view, I became exceedingly uncomfortable when I came to the CVS tag dialog. The problem was that I was uncertain which files it was going to tag.
It would be really good to have a dialog containing the list of files that will be affected for any CVS operation which affects the repository directly, i.e. commit, tag, branch, etc.
I've already created a JIRA issue, http://www.jetbrains.net/jira/browse/IDEA-12932 , but I thought this might merit some discussion in the wider pastures of the EAP forum.
