Feature: user configurable icon in your new toolbar for non-common components used in the current design

[vgreff]

It would be nice to be able to have some user configurable icon in your new toolbar for non-common components used in the current design. For example I was using Schmidt trigger and real amp ops and they don’t have a shortcut.
I know I could assign a permanent shortcut for them but I don't use them that often in general.
But in the current design I use them a lot so it would be nice if I could right click on an instance in my current schematic and assign it to a user defined slot (0-9) and use the slot as a shortcut too (may use numbers 0-9). and they would on the toolbar too under a dropdown like the one for the logic gates for easy selection.
