-Can you create game "shortcuts"? (ie. shortcut launches said .exe on the right screen, maximised and set to revert back to original display settings when exited)
Short answer; not yet. You can read more about it
here. The feature will, if everything goes as planned, be implemented in a future version.
-Is the Win 7 Taskbar (on the secondary monitor) rendered identically to that of the default one, AND is the functionality intact/the same?
Pretty much. It looks identical, it support themes and the glass effect - only thing that is different is that the preview windows doesn't line up the same way, and the location of each task is a little different.
-Are there 2 buttons added to the top of each window? (like that of Ultramon's, ie. Send to other screen, Span)(i believe there to be 3 w/ DF, though I mentioned it for clarification)
DF took this one to a whole new level. You can add a whole bunch (really big bunch as well) of icons up there, and you can customize every single one of em - as well as customize the amount of icons displayed. It's called
titlebar-buttons.
Theoretically, you can add pretty much any function to a button up there - including those you mentioned.
And if one feels finger-happy today; a nice straight-forward explanation as to where Win 7 and Multi-monitor support are at currently would be nice (though I'm sure my 3 main question's will suffice!).
The W7 support as today, it very good. No compatibility problems, however the OS is new and there's always bugs but the creator is very good, and fast when it comes to bugfixing etc.
I will be purchasing DF if my issues aren't... well, an issue. More importantly though is the fact that this is a deciding factor on whether or not i will upgrade my OS. Otherwise I'll stick with Vista till either UM or DF become more feature-rich in the Win 7 environment.
If you purchase it you won't regret it. I've used ultramon myself, but I changed to DF when I moved over to W7. I usually try to use free apps, and well, this one is also partially free, but all the good features are let out in that version, obviously.
In short; this app is well worth 20 bucks, and you won't regret it - I assure you!
