I personally like the new tabs. I like seeing more information then previously like the pie chart or analysis results vs. current state. I also like that this information is on the default tab, it's better for new users. I do agree with thm though that there should be the four different defrag options. I know that you can defrag freespace through the advanced menu but it should be a more accessible option. I do have a couple of additional comments about the latest version though.
-Should add a timer that shows time elapsed and estimated time remaining.
-The percentage complete is not very accurate. It jumps around a lot and then stays at a certain percentage for 40 min., and then will jump quickly again.
-When you maximize the window, the UI does not resize accordingly. It just stays the same small size in a now big white window.
-I also really like jd's idea. "When you Analyze, have Defraggler suggest whether or not you should defrag and which type to use."
-Add in a scheduler for analysis. It will automatically defrag based on the analysis results given using the above method.
Overall this was a nice release though, good work.
