Just a suggestion for convenience: There is already an option to open and close the bazaar, but it would be useful if we could organize some items in the bazaar for sale (what would be open) and others in "storage" (what would be closed). The key here is that the items and price would not have to be re-inputted.
Not to say that it is impossible for me to stick my junk in my bazaar for sale overnight and to take my other items out, but the more items there are already in the bazaar... well... I'll just say that bazaars are already pretty messy.
