methods to select a bunch of files at ones

[hpvd]

If one once has a great file uploader like uppy, there will be use cases where more then some files should be uploaded

• load files for backups to a server
• transfer a complete "project folder"
• ...

with this it's important to have methods to select a bunch of files at ones
e.g.

• select a range: only click on first and last file
• select a complete folder

sure from local this is possible via drag and drop. But should be also supported for other location

common ways on this:

• allow strg + mouse click (each file)
• shift +mouse click (first and last)
• "drawing" a light tented transparent rectangle over files by hold mouse button and move mouse (from upper left to lower right corner of rectangle): every file (icon/preview/name) completely covered by the rectangle is selceted.
