I only just now noticed that the PSu tooltips are far much more detailed than I knew. I also did not know that they work even in sub-windows, providing detailed information for aspects of PSu not necessarily mentioned in the help manual. Coming from IDI 5 I basically until now ignored the tooltips, not realizing the explain parts of the program in much more detail than I had anticipated.
Perhaps you all know and have used this resource - in that case: sorry to point out the obvious

But in case that, like me, you managed to overlook it a screenshot below...
Cheers,
