1. The most important is speed(performance). So if possible, can you retry to optimise it's speed? par exemple, use a stronger algorithme of the compression (7z,rar)
2. The same reason, you can optimise the performance of DBText, DBEdit, and a light DBGrid, I know it has much work, but only with these three components, the developpers can make a MIS with good performance. At least, DBText and DBEdit are not very complex.
3. Outlook Style. the same component as TRzGroupBar in Raize.
Thanks...
