How are the limits working for you?

I've limited most of the user input fields.  When you enter an item, there's a limit on the name length of 32 characters.  Some fields allow 512 characters and some 1024.  Typically, the tools with 2 windows allow up to 512 in each window and the tools with 1 text window allow up to 1024.  These numbers seemed reasonable to me and I've been able to work within these bounds.  I'm wondering if anyone is having issues with these limits.  Thoughts?
