Append spaces on blocks of lines to make them the same size.
Features
Given one or more groups of selected lines, this command would find out the length of the longest one and append spaces to the other lines, giving them all the same number of characters.
This is intended to make column/rectangle selections and operations more friendly.
How to Use
EQUALIZE -- Select lines and hit ctrl+alt+l. All selected lines would become the same length by adding spaces on the right.
UNEQUALIZE -- Select equalized lines and hit ctrl+alt+u. Exceeding spaces on the right of the lines will be trimmed.
