TOPIC: Useful wishes for tenders

I have some minimal but useful wishes.
1) If someone register with joomla account on the site and register for event, don't show button register for this event or link to the registration, because this account has already register for this event, i think this is very useful.
2) Second wishes for example event has link to the article, and this article has some attachment files, and my whishes that this attachment was available only after proceed registration for this event, and available only for user who register for this event

If this two minimal wishes will be in your product I without delay buy your product, because your product very useful in organization tender on the site, but each tender,has tender documentation which will be available for download only after registration and only for people who registed for this tender.
Thank you in advance, I wish this minimal details do your product better.
