Market- it would be great

[Brontobeuf]

... to have a "cancel all" button to remove every single card you got that you are selling.
Doing it one by one generatesa lot of requests to the servers and is slow as hell.

I don't know how realistic it is, but, it would be really great.

I know this has been mentioned before, but a hide all cards you have more than 5 of on the buy side and less then 5 of on the sell side button would be much appreciated.
