Add confirmation step to delete and clear drawing board

[AbigailDawson]

The drawing board can be deleted instantly by pressing the Delete key; if this is done by mistake it’s impossible to restore the table unless you undo immediately.

» the same is true for clearing the board with the trash icon; this cannot be undone even with undo

Possible solutions:

• add confirm delete step when delete key is pressed (same for trash icon?)
• record version history in whiteboard (similar to scribbles) to restore prev. version if needed

Hi @AbigailDawson ,

Hope you are doing good. I am Basu, a Software engineer who loves doing open-source contribution. I recently came across the Huly platform and feel it has a lot areas where contributions can be made. Although, there were'nt any issue after filtering the ISSUES with "Good_first" and "help-wanted".
Hence, wanted to check-in for any issue that you currently aware of, where I can make a possible contribution.

Wish to hear back from you soon...

Thanks
