Feature REquest OS3 gui: possibility to select what files to delete with checkbox

[stealthizer]

In the files and cloud menu the action to delete a set of photos is determined via clicking over one of the presents set and then move to the right pane, ensure that the selected set is labeled in there and press DELETE SET. Also, to delete all the sets, you can press the DELETE ALL.

What I propose is that in the file list there is a checkbox for each file, so you can check multiple files and apply to them actions on bulk, like delete, maybe download... and with a master check for all files, you can mimic the "delete all", eliminating one button from interface. Also, maybe this could be used for cloud operations (bulk upload)
