Instead of having regular and tall as the window sizes, can the size be a number based on something like how many standard lines of text can show up? Right now the standard size can probably hold like 6 lines? So that would be a size 6, and it can be increased by one up to a certain number. Would just look cleaner because it can avoid having the extra blank white space on the bottom.
It seems to me that it should be possible for UI++ to evaluate/count the items on the window before defining its size. That would allow the window to be (optionally) sized dynamically (with a min/max value).
How about an option to size the UI++ window to be the same/similar size as the task sequence password entry and task sequence selection windows?
I prefer to have a little more room on the likes of info screens to display descriptive text to the user. I squeeze several lines of text into an initial info window and it's not a good fit right now. I would prefer not to have 2 info windows for the job or users may get impatient with too much "noise" .
