I'll be honest, by clicking on a link here above i've found mssqlXpress, what is doing quite what i wanted.

I wanted a tool so maintain on a visual clear way all my procedures, triggers stored in a database. The Edit Design in this app is quite the same as the one in EntrMgr but with all the data on 1 screen.

Thx for the effort, if you know similar products to mssqlXpress, always open to suggestions
