One less bug is still an improvement. 
I haven’t downloaded the latest commit yet. I am being more careful about staying within my monthly bandwidth limits.
In the prior commit, this is what the windows look like. Top is PF’s main window. You have minimize, maximize and close. Middle is the module parameters window. Notice that the x is really and permanently faded; means that it is disabled. Mouse over doesn’t light it up either. The next one is an active open window. Active buttons are bright. If you could make the parameters window behave the same way as the open window, that would be great.
PS I downloaded the latest commit. It took a much longer to decompress; might be the way it was packaged or due to Defender (my recent thread Reasons the app isn't running well on Windows). The startup time is much quicker now. 
I like the close button. Unfortunately, it is out of sight, in the bottom right corner.
PPS Might be too soon to try [tools/OCIO transform] initial implementation]. When I create the layer, the preview gets distorted with all sorts of things, depending on what I select; e.g., tiles, dots, etc. Clicking on one of the boxes in the GUI crashes the app. Each time I try again, the distortion is very different in appearance.
