Hey this is awesome. I missed your original post (been off the forums for a while), so thanks for the plug!
I fired it up, and seems to work fairly well so far. Needs branch support, but I guess there's the command-line. (Bash does great auto-completion for Git branches though, better than entering them on SlickEdit command-line.)
I've been using a mixture of command-line, IntelliJ IDEA and SmartGit for my increasing number of Git projects. No clear winner so far, no one tool that gives me a seamless workflow.
I've been using Intellij IDEA 9's "Tasks/Contexts" feature a lot lately. It lets me switch between views of open sets of files. (I believe this is inspired by the Eclipse "Mylyn" plugin.) With Subversion, it also switches the default changeset for a commit. So outstanding edits are "automatically" categorized for version control by topic. It works really well.
It would be awesome if SlickEdit got such a feature, and perhaps could also combine it with topic branches in Git. There's a lot of work I'd be more inclined to do in SlickEdit if it supported that.
