The library teams are already working on that feature. Until it is fully available why don't you check the library or the lexicon of your site? I'm sure you will find many answers there (:

Try to change the size of your screen (for windows strg & + / strg &-) This should solve it.

Trading the chocolatefrog cards is already planned, and we are working on it. 

But gifting money will never be a thing, for the reasons already mentioned. This function could be abused by making countless new accounts and just transferring the money from themto the main account. 

Please owl your library leader if you want a specific book to be added. If you want to write books yourself you can always apply to become a librarian. For searching specific words I suggest you use the search function of your computer (for example strg + f for windows).

Is this still a problem?

Unfortuntaly there is no evidence that Hogwarts ever had a ballroom, so it would be not very realistic if we added one. Most balls, like the yule ball took place in the great hall. If you want to host a ball on your site we suggest you ask you plot team leader about this idea, we're sure together you can create a wonderful event in just the right place (:

Why don't you just send an owl to your beloved witch or wizard? I'm sure they will be more flattered by a text that you've written just for them than by a automatically generated question. For dates there is always a free table at the different cafés where you can just start a topic with the person you are dating and if you want, even with more persons (:
