Some ideas...
Could an option be added in smtube2.ini be added to load more results per page and also set the image size. Perhaps an option in smtube2.ini?
Using Lt-Arrow/Rt-Arrow to flip between pages might be faster than clicking an icon on the screen.
It seems youtube-dl has a problem with unicode filenames with Windows. The video is downloaded but only given the name of the video ID. If the Rt-click menu had the option to copy the videoname to the clipboard, then it would be easy to rename the video properly. Any way that could be added?
Is it possible to remember the chosen Catagory, Region and Language between sessions?
Any way to do a reverse Date sort .. oldest first? I don't know if that's a 'Youtube' option, or not.
