Better Collection Organization

I was wondering if there was a way to remove bills & coins accidentally added to my collection.
I would also like to suggest an additional tab to show all the coins owned by the user. A great example of this is Collectiblend's structure for displaying & editing/auditing their collectors collections. Also uploading edited spreadsheets to override the current content might be nice.

"​I was wondering if there was a way to remove bills & coins accidentally added to my collection".
Go to a page and on the quantity press delete.

​"I would also like to suggest an additional tab to show all the coins owned by the user".
At the top of the page is 'My coins'

Example:
Before
During
After

If at the top of the page all you see is
Coins / Banknotes / Exonumia / Swaps / Forum / Numisdoc / Outings
on one line, there is a second line above that - at top right will be 'My account' with
three lines - click on that and the second row will be shown. To keep it like that click on the 'pin'.

Once you have clicked on 'My coins' then click on the 'Coins' box with a number in it.
That will show what you have, and you can change the quantities from there.

"Go to a page and on the quantity press delete." ​You're describing a system that doesn't exist for new users. They won't see the example you show. They'll see this:

To delete an entry click the delete icon on the right.

"Once you have clicked on 'My coins' then click on the 'Coins' box with a number in it." This doesn't work with the new system. Need to click on the OK icon.
