Rated 4 out of 5 stars
very useful extension but still annoyances to be worked out. besides the ones already mentioned, using the right mouse button to drag will constantly trigger the context menu from scrolling operations (maybe due to a worn out mouse), whether or not you use bar emulation mode. using left mouse button is out, since it interferes with even more operations and rendering, which is understandable but really limits the functionality of this great addon.
to be fully usable, compat mode needs to be extended further (to avoid flash applets and such), with more event detection to prevent interfering with these buttons in their basic functions.
