it would be cool to filter shows by date so we can see what's on during a specific timeframe.
Absolutely, similar to what songkick does. Where you choose a city and a time frame and see what gigs are happening then.
I often have friends visiting from other places and it would dope to see what is going on during their visit
Checked your tracked/suggested artists on a calendar view
Absolutely agree, hate having to scroll for days just to find out whats on in two weeks.
