About this Add-on
Consider this scenario, and you will understand why this was made. First, select a colour from the colour picker, oh, say, blue, and type some words. Now, change the colour to red and type. Now select some of the text at the beginning of the line - to change the colour to the "last-picked colour" you have to use the colour picker again - well, not with LastColour! Just highlight the text and make whatever words you like to be the last colour you picked.
You can also set a default "last-picked colour" in the options menu for the addon.
I use this one every day!
It has a bug that when the coloured text is inserted, it also inserts an extra < br > in the html; however, this will be fixed in the next version 1.2.
