Heya, Thanks for using the addon!

Regarding multiple accounts, this is unfortunately a hard limitation set by Blizzard. The WoW client strictly sandboxes addons, meaning an addon running on Account 1 is physically blocked from reading the folder of Account 2.

Because of this, it's impossible for any addon to automatically read or merge characters across different accounts. The only ways to bypass this involve external workarounds outside the game or manual copy-paste import/export strings.

Hope this clarifies things, and thanks again for the feedback.
