Allow adding files inside table cells

Hello!

Thanks for the great work!

One thing that limits organizing our department is that it's hard to "group" attachments, because they are being added at the block-level and thus cannot be added into tables.

In theory it should be easy to shorten the file boxes when in a table. I tried it quick-and-dirty in the Browser-Inspektor by adding:

the css attribute display:inline-block to the box:

Maybe this is worth of including.

Thanks,
