If you use Thunderbird email client and have many email accounts/folders, you will someday wish you could re-arrange them in your accounts view pane. Thunderbird by default displays the accounts in the order in which they were added, and does not provide a control panel option for re-ordering them. But there is a solution and for me, it works perfectly.
Download the FolderPaneTools Firefox extension to your hard drive, and then load it via the Extensions tool in Thunderbird. Once restarted, Thunderbird will offer simple “move higher/move lower” options for all of the email accounts in your view pane. In just minutes I had relocated my most often used accounts to the top of the pain, and then re-arranged those so the shorter ones were higher than the more complex ones, leaving me with my priority accounts visible on-page when Thunderbird loads. Awesome.
