This is what I mean with a filter row, what'd ya think? Better than tabs isn't it?

This allows building basic filters:
- Date column: allows selecting "All", "Today", "This week", "This month", "Range..."
- Type column: allows selecting "Received from", "Sent to", "To yourself", "Generated", "Other"
- Address column: type whole or partial address
- Amount column: enter minimum size of transaction
I'm also going to add a "clear filter" broom button to the right.
Note that this is just a prototype still, please let me know your ideas and comments before I start implementing.
Nice work, would it be possible to add "BTC" to the balance? And will the amount column also work for the sent (negative) amounts?
