heya Gary. yea, it opens another explorer window, but ... i'd really call it a duplication IE as it opens the instance with the same loaded webpage.
What i would really like would be for the desktop preview to have a sort of "color-coded-type-grouping" of a particular IE along with its included tabs, as all the same "highlighted color".... sometimes the titlebar will not specificly tell me exactly which instance or website by name that i have opened. Sometimes its just a guess as to which is a tab and which is the actual "instance" of Iexplorer.
Something comes to mind.... take for instance a RTS game, C&C to be exact. If i want all my tanks grouped i can group them by selecting ctrl+(designated #)... humvees another # and say troops another #... this way i can say (alt+tab-like) between specific grouped groups, rather than say just a single tank or click/drag, of course, or guessing which humvee has the troops that i want to drop off per say. Time consuming to a degree.
As of now, its kinda a guessing game if you have ALOT of IE's + tabs opened up to where the desktop preview is no longer available/useful.
Tis why i offer up the possible color-coded experience or something to the liking to differenciate better in my case.
