[Koha] Biggest Koha Problem

I work for a small rural library district and we are looking at possibly migrating to the Koha system. I wanted to ask active users of Koha a question: What is your biggest problem/bug with Koha? Any brief description you could share would be helpful and feel free to contact me off list. -- Josh Westbrook Prescott Library Mngr/District Technology Mngr Walla Walla County Rural Library District 37 Jade Ave Walla Walla, WA 99362 joshw@wwrurallibrary.com | 509.527.3284 http://www.wwrurallibrary.com Don't worry about the world coming to an end today.
