When you're listing credits on the marketplace at the moment, your quantities are predetermined by the drop down box, i.e. 1-10, 15, 20, 25, 50, 75, 100 etc.

This is fine at the lower increments but when you're at the higher levels, having the option to specify 28 rather than having to do a listing of 25 and another of 3 would just be a bit of a time saver. Not a huge issue, but it is a bit of a pain when you're undercut by $100 multiple times an hour and you have to cancel, relist, relist. If I could specify the exact amount I want to list however, problem solved and the additional clicking is redundant.

In addition, could we have an option to modify our listing rather than cancel them? As above, if I could just have "adjust to:" and insert my new price, this would prevent the need to cancel and relist.

Nothing essential by any means but it would make life a little easier. 

Fantastic, much appreciated!
