Just download your program and I'm impressed. Do a little programming in Delphi,see you done your homework on this program. Like the layout and it has a clean look. Couple things you might add in future.
1- Maybe a small button to clear the search box?
2. After Search box is cleared the list defaults back to first item in list?
3. Maybe some background options for list box ?
4. Option to show search box if tool bar is hidden ?
5. Option to control List box fonts, colors?
Again let me say you have a real nice program,still checking it out.
