Good question. Problems with communicating between "real database developers" 
and newbies is not so depenent on our idea of user levels:

- Look that if caption is not available, Kexi falls back to latin1 name 
everywhere in the GUI (in particular, for table and column names)

- always displaying latin1 name to newbies does not mean they will choose 
reasonable short name that advanced user may prefer. Thus it can be better to 
stay with automatically generated names so advanced user at least will see 
what to expect from a project created by a newbie.

In short, by hidding the name I have chosen to be as similar to other popular 
tools (MS, Filemaker) as possible. The target audience comes from spreadsheet 
world, so it's a priority to hide technical storage-related stuff by default.

One thing we could added to the dialog
http://iidea.pl/~js/kexi/shots/0.9/object_save_as.png
for the 'newbie level' is a "specify name" checkbox or "advanced >>" button. 
What about this?
