I really appreciate the possibility to select now multiple files at once in "Files" tab. I can also drag and drop them all at once now then into a project tab or open them all at once via context menu option "Open".
Just closing them all at once is still cumbersome. I'm missing a "Close" option working just the same way.

Please compare this also with my enhancement request in thread "[13.0.4][64 bits] project items and context menu"
