@@ -20,17 +20,8 @@ Plans and ideas for 1.1:
 * offer a) no alignment of partition boundaries at all or b) legacy cylinder
   alignment or c) sector based alignment (the name is misleading, though)
 
-* the size dialog base is a mess with its confusing free before/after stuff.
-  redesign to use first and last sector and nothing else and calc the rest from
-  there.
+* offer to skip aligning the partition when creating it in that details widget?
 
-* once the above redesign is done, allow the user to adjust first and last
-  sector directly. maybe offer a details dialog widget. maybe also offer to
-  skip aligning the partition when creating it in that details widget?
-
-* write a KFormattedSpinBox widget to allow qint64 instead of int and to show
-  sector numbers nicely
