It is good software. Thank you very much first of all.

When excepting some files when downloading.
1. Select to removing files in "Files" tab of the bottom.
2. Right click
3. "Priority" -> "Off" click.

I need this.
1. Select to removing files in "Files" tab of the bottom.
2. Press "Delete" key.

Thanks again.

Delete is not, maybe space? But anyway you know you can click in green checkbox to avoid download? Is just one click. But more shortcuts will be useful anyway.

If case there are so many files and I just wanna few files, It may useful.

I think 'space bar' toggle is such a good idea.
