I wanted to vote today again ( I am on version 0.4.7) and I didn't vote at the end.
1.When I go to the top delegates page I can't see which delegates I have allready voted, only if I wait a few minutes!!! (is it a bug?)
2.Sometimes I am not sure if the blue or the white upvote hand represents the vote... its confusing if you see both colors (maybe better use green color for upvote, white for no voting and red for downvote*)  *I thought we can not downvote 

3.To give a motive to users to pick up "Vote All" or "Vote Delegates Recommend"... lower the fees for these options... 
       TRANSFER FEES EXAMPLE:   
   1.Vote as Delegates Recommend    fee=0.1 BTSX
   2.Vote All                                         fee=0.2 BTSX
   3.Vote Random Subset                    fee=0.3 BTSX
   4.Vote None                                    fee=0.5 BTSX  (let them pay for maximum privacy  

)
   maybe the order can change a little... (depends on "networks" prioritys)
PS make your suggestion on this thread so we make voting a better experience
