Some PDs will have either (a) many probes (e.g. 32 or more) or (b) many options, or both. In such cases the dialog for the PD probes/options will get so huge that parts of it won't be visible on screen anymore (including the "OK" button etc).
Thus, a scrollbar would be good to have for this dialog.
The same applies to any other popup in PulseView. E.g. the probe config popup can also have *many* channels and/or channel groups and such, making it completely unusable on some devices without a way to scroll.

Fixed (for the PD channels/options) in f52ffd9d82b45313836c5e612c7cc48982ced529, thanks!
The "Add decoders" popup has been replaced a while ago and that one has scrollbars already.
I've filed similar bugs for the remaining areas that could probably use scrollbars: #1412, #1413, #1414.
