(I have posted this suggestion before. Nag, nag, nag)
I still would like to have scrollbars on the right hand side of the Defraggler screen for the tabs "Drive map", "Search", "Health" & "Statistics" when the amount of space is insufficient to display all information. Just like the tab "File list" has (also on the right hand side).
Another suggestion for DF is that DF also could make suggestions whether or not the SMART values have risen/fallen to a dangerous level. Like the program "GSmartControl" (GSC) does. If the SMART values have reached a dangerous level then GCS shows those values in a red (redish) highlighted line.
