Kudos to the people working on the uploader. Really an excellent tool!
I have two suggestions for the developers:
1. The most important requirement is - to enable "Ctrl" and "Shift" buttons to select multiple files in the file selection box. Right now if I have to select multiple files, even if they are consecutively listed, I have to click on each file and then click on 'Add to Queue'. If I can make use of "Ctrl" or "Shift" buttons, the click count can be significantly reduced.
2. I suggest that another option "Remember the last accessed folder" to the list of Options already present. Currently, it remembers the last folder that I uploaded from by default. But it would be better to have it as an option.
Hope these are included in your next release
