You can reorder all the entries via Drag & Drop (with the exception of the History, which is always sorted chronological). Click (or Alt-Click, depending of the iCab preferences) on the list column headers to sort the entries alphabetically.
Using the contextual menu (Control-Click on the list column headers) you can hide columns or you can switch them on again (see the image below). The exception is the very first column, which can't be hidden (similar to the finder where the column with the file name is also visible all the time).
You can change the widths of the columns by moving the edges of the column headers with the mouse.
The order of the columns can be also changed by dragging a column header to the new position. The only exception is the very first column which will always remain on the first position (similar to the finder where the first column with the file name will also remain at the first position).
