there should be a uniform system, something like that if you have lived in one country and have paid taxes there (fiscal residency) for more than X years you should be able to vote local elections.

A EU citizen living in the UK for long enough, and with a plan to stay, should have a say on the decisions of that country.

Yes, there is citizenship, but rules are all different and are made every more complicated as we speak (I like in Sweden, where the case is clear).
