Productivity and Firefox's Tab Groups

So recent habits to increase productivity involve segregating focuses.  I'm trying to use Firefox's tab groups to help separate life stuff, GSOC stuff, Thesis stuff, and other work/school stuff.  However, I have a couple complaints.

• Pinned App tabs appear on all Tab Groups.  So, I can't pin Google+ to my Life one and have it not appear on my work-y ones.  I have to unpin it to prevent the potential distraction, but then I lose all the benefits of having it pinned.  I want pinning to be per-tab group, not global.  
• Update: Bug 722375 already exists.
• ctrl-w, upon closing a tab, takes you to the last one accessed globally, not per tab group.  So, if I hop between tab groups (e.g. I want to check if I've received any IMs or e-mails while in the past two hours of work), and then go back and close a tab, I suddenly hop to another tab group.   I want ctrl-w to be per-tab group, not global.  
• Update: This is probably actually bug 582872 and its happening might be anomalous to my old, aged profile.
• ctrl-` for switching groups seems slow.  So slow.  Like a whole second slow

I was thinking about using "firefox -P profilename -no-remote" so that I could instead create separate profiles (and use -no-remote to use them simultaneously) but this apparently isn't working on my installation for some reason.  UPDATE: I hadn't removed .parentlock, as I had forked my default firefox profile while it was running. Whoops. :)  I can do this now.

I can do that with Google Chrome, but I really benefit from having tabs laid out in a vertical tree-style tab view, as an extension in Firefox gives me.  Sigh.

I'm also beginning to miss the static workspaces of GNOME 2.x.  GNOME 3.0 has dynamic workspaces, but they're in a linear list.  I'd like to keep some just constantly there, and I'd like them in a grid, so I can spatially orient my work.

It's not so bad.  I've been being pretty productive without these enhancements, I just want to be able to focus more on specific tasks without switching so much.
