I've been a big fan of Electrum, thank you to the developers & those hosting servers!

I am running Electrum on 2 different computers. I noticed that when I updated Descriptions of all my transactions on computer#1, that these descriptions did not sync to computer#2.
Computer#2 shows bitcoin addresses instead.

I'm pretty sure they should sync, because I can see a few of the older ones do have custom Descriptions. (Although it is possible that maybe these were 'notes' I added to the transaction at the time I sent the bitcoins)

On one hand, I suppose my manual Descriptions aren't going to be on the blockchain, so they would have be stored locally. Is there a local file I should sync to computer #2?

(Computer#2 is version 1.9.7)
Thanks
