Everything Button Guy has created has worked no problem for me. The only missing detail is perhaps having the ability to change the icons, or perhaps have a simple few icon sets.

Ideally, to have something like, "The Button Guy Suite" that encompassed everything he's created with an options page featuring the ability to turn things on/off, reskin the icons to a couple themes, hotkey/macro/magic, toaster oven, etc.

the day after

I missed it, but now it's back. Mtks.
How about a "Close Tabs to the left"-Button?

simpe & works
