Search in Scratchpad

The Scratchpad is very handy when importing additional icons that do not exist in the current icon sets (Azure icons for example). However, once icons have been imported into the Scratchpad, I cannot use the 'Search Shapes' function to find the imported icons by name.

It would be a great feature add to the extension if we can use the search function to find shapes in the native icon sets and Scratchpad.
