idea for csgodouble withdrawing

Hello, i have about 90k coins on double and i want to withdraw keys with that, now doing this is a b*tch because they are usually gone. So i want to give a couple of ideas for the devs on csgo double that they could implent to the website:

• If you choose for example 5 keys but 2 are already taken you will still get a trade offer for the other 3 instead of it saying item not available ( 2/5). Where you have to refresh the page and then there are no keys availible.

• Able to request keys, so you can for example request 30 keys then when there are keys they will send them to you until you have gotten the 30 keys you requested or something like this :)

Hope to see comments with your ideas and i hope the devs will implent them to make it easier to withdraw wanted items ( like keys).
