Better Script management, script profiles.
Most of time i use like 6 trackers to search for content, with The Pirate Bay shot down by police it's 5.
However sometimes I am desperate to find something and I enable more or all Scripts.
What I think is missing is custom Script profiles(default, more, custom, so on each with different check boxes checked).
Also Script categories especially for public trackers(easier to check whole category):
Most reliable(in my opinion please add yours):
Kickass, BitSnoop, 1337, h33t, rarbg
Not so reliable:
And to be honest most of public trackers goes here
Low reliability:
Sumo
Limetorrents
Monova
Offline:
TPB(was most reliable +)
PublicHD(was very reliable +)
Also discussion about public trackers reliability would be nice.
We can also start list of not yet or never will supported trackers to share knowledge and spare time(I am not sure if I have not seen one).
