If I have multiple wallets does the settings menu affect all wallets? Specifically, if I enter a host in remote server, do all my wallets have to delegate to that same remote server?
settings does effect all wallets, but if you start one account harvesting on one server and then change IP, the fact you changed IP wont stop the account harvesting on that server. so settings are global for your client but if you do something and then change, the change doesnt have any effect on what you have already done. unless we are talking about local harvesting. if you change from localhost to an IP while loca lharvesting it will stay harvesting, but when you turn off local nis it stops.
So if I enter a remote server in settings which only has space for one more harvester, then I change wallets and change the remote server in settings to another one that has space for one more harvester, will the first wallet still be delegating to the original remote server? I'm not sure this works because when I switch back to the fist wallet it does not say it is harvesting, it says start delegated harvesting.
thats how it should work yes. when you activate delegated harvesting, a proxy key is generated which holds your importance and that key is sent to the server that you are connected to at the time when you "start delegated harvesting". so even when you disconnect from that server, its still holding the proxy key. so when you swap over to the other server and "start delegated harvesting" the same thing happens.
