When I developed the bar-style slider timers, I stopped using any sort of digital timer in the UI as well. I agree with you that bar timers are much easier to use. It looks like the digital timer included in the Slayer UI is actually one of my older timers, since I can see my comments in the XML file. To remove it, you can do the following:
Open
EQUI_GroupWindow.xml in a text editor, and scroll to the bottom. You should see a section as follows:
Code:
<!-- BEGIN timer pieces -->
<Pieces>TimerHour</Pieces>
<Pieces>TimerColonA</Pieces>
<Pieces>TimerMinuteA</Pieces>
<Pieces>TimerMinuteB</Pieces>
<Pieces>TimerColonB</Pieces>
<Pieces>TimerSecondA</Pieces>
<Pieces>TimerSecondB</Pieces>
<!-- END timer pieces -->
Go ahead and delete the above lines from the file. This will cause the digital timer to not be displayed at all (there will just be a blank area where it used to be).
Edit: Wanted to add that you could clean up the file even more by removing all timer-related XML from the file. However, doing so would be purely optional; removing just the lines listed above is enough to remove the digital timer from your UI.
