Hello ! Just a quick suggestion...
It would be nice to be able to replace a previously added icon in the icon picker.
As it stands, if we want to update a custom icon, we have to remove the old one, add the new one and then go through our entries to update those that used the old one.
It would be much simpler if we could, for example, select icon #10 and just replace it. All entries that use icon #10 would be automatically updated.
Have a great day :-D
