💡 Request - Remember Login in Browser

### Area

Proposal Pillar

### Is there new design needed?

Yes

### What?

Simple request to use a cookie or some other method to persist sessions on the same browser without having to use signData every time.

### Why?

Many users (such as myself) use a hardware wallet and it takes a few minutes to sign each time. It's a bit cumbersome when I want to browse the Proposals section throughout the day to have discussions, but I keep finding myself needing to sign repeatedly.


### How?

A cookie seems the most straightforward to me. Some other type of browser local storage might work too.
