You know, I applaud MS for aggressively following web standards and all these days, but then I find that the IE11 being pushed out to my peeps' Windows 7 desktops:
1. No longer has the little blue compatibility view button in the address bar
2. Doesn't remember the compatibility view list from IE10
3. Requires you to now infer the need for Compatibility View for a site and enable it thru a 4 step process.
4. deletes this list if you clear browser history
It'd be nice if we lived in a world where Compatibility View was so rarely needed. But we don't. So now I have to explain this arcana to my users, or consider rolling back to IE10.
