I guess many people know the issue of having a screen saver forced active after a some time through a group policy in a corporate environment.
This is usually done to make sure systems are locked during breaks if people forget to press Win L (or Ctrl Alt Del and then Enter).
The latter I have also found Kaliro Screen Control which can do the same thing.
Taiga is an open-source desktop application for Windows.
It automatically detects the episodes you're watching on your computer and synchronizes your progress with online services.
While that may well help IT security, it turns problematic when giving presentations for extended periods of time.
Having to move the mouse through the presentation pointer every few minutes or dash back to the PC once the screen saver has kicked in, again, is simply annoying.
