Just wanted to check its not going to be a problem.
It's an HD wallet so all the old addresses are completely valid and will always be valid with the same seed. I use old addresses on there quite often and it all goes fine. It'll combine outputs from the old address with any other ones if you've received on other addresses.
If you want to check, not that you need to, click on accounts and then sign message and it'll show you all your addresses.
Does the wallet have a certain method to consolidate separate accounts and keys into one balance that would then go more cheaply then any address that has multiple in/out transactions on it. I would guess this isnt possible as it has to be cleared via the blockchain which is another fee but if it has these multiple addresses anyway is it possible to clean it up a bit perhaps.
I should already know this but I've been using alt coins for years with block time under a minute and a penny cost. However the non crypto company I deal with now prefers I send from a BTC private wallet only, to the point where its a bad price if I dont so its worth me finding out the cheapest method for the future.
