absolutely brilliant. Works really great, now looking at keeping one workspace to store reference addresses but I've found in some workspaces, the tabs vanish.. It's not permanent, I've brought on back accidentally but I'm no sure how - ) I think I started to type the address from memory and it did an autocomplete and reappeared so probably I'm missing something. Not sure what Tab islands are. Also sometimes tabs seem to contain a list of addresses

Any pointers?
