I have tried copying an item from the library so that I can edit it and I have edited and existing footprint and saved it but I cannot work out how to find it again when I come back into EasyEDA. I have tried searching on the name of the item e.g. ESP-03 (NON-SMD) but cannot find them.
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Symbols and footprints that you have edited will appear in:
Shift+F > Library > EasyEDA > Symbol > Workspace
or:
Shift+F > Library > EasyEDA > Footprint > Workspace
