Questions are actually good as they lead to improvements. Sometimes, the improvements are already under way, but it's never bad to ask regardless.
With me, a little bit of everything is already under way, if only in my head. Currently, Lestrade's is in the implementation phase. I don't mind suggestions, but I'd rather I get them after I consider the site 'ready' to take on the trading community.
Related to that, all I want is for my wishlist to sync with Steam either automatically or via a simple push a sync button
Automatic syncing will come later; right now I think the Sync button (for libraries) is good enough and allows me to focus on other things. Syncing with Steam wishlist will come soon, too; but I thought I'd do library syncing in 5 minutes and it took me a day, so I can't promise anything, except for the fact that I'm doing the 'internal work' I need for it.
AND a way to at sync with my barter tradables list periodically as well (or at least be able to use check boxes as I mentioned in my other comment regarding this on another thread). What I don't want is to have to manually remove hundreds of items one by one.
Right now you can at least easily remove all your wishlisted items that you acquired in the meantime. (See my upcoming post on 'What's up?')
