The next step then is to save as a Work Space, that way incase you ever need to reinstall, or have any problem with PSP9 you can reload your tool bar/work space just how you wanted it without having to go through all the buttons, commands and/or adjusting your color window, layers windows that usually reside on the right hand side of your screen.
File>Work Space/Save and then name it...mine is Traceyworkspace, then if PSP ever defaults to it's workspace mine is saved...

Then I just have to reload it!!!
Big time saver!!
Another one is to take apart the tools like the erasers, selection tools...ect.
I hate having my tools under a drop down arrow menus, I know what I want to click and do not want to click twice to get it. You can use the same method as above by dragging and dropping them to the tool bar, then you also need to take out the duplicate tool under the little black arrow by dragging that one back to your customize window.
