True Launch Bar allows changing icon for just about any button. To change icon, right-click on the item to be edited, then point to the “Appearance” item on the context menu, and then select “Change Icon”. True Launch Bar will open the icon selection window:
To select a file or folder with icons, click on the “Browse…” button and then select the “Browse Icon File” item on the menu to select an icons file or folder. True Launch Bar supports the following icon file formats: ICO, ICL, DLL, EXE, CPL, BMP, PNG, GIF, and JPEG.
The selected file or folder will appear in the “File name” field, and the icons from the file or folder will appear on the “Current icon” list. Select the icon to be set for the button and then click “OK”.
You can change the icon size by selecting the desired size on the “Icon size” popup list. This size will not affect the size of the icon on the button.
To
find necessary icons quickly, you can bookmark frequently used icon
files and folders. To create a bookmark, click on the 
button, then select “Create Icons Library”, and then
enter the bookmark name. True Launch Bar will create a bookmark to
the file / folder. To quickly open a bookmark, click on the button and then click on the desired bookmark. To delete a bookmark,
select the bookmark to be deleted and then click “Delete Icons
Library”.
By default, True Launch Bar already has a bookmark to Windows basic icons, such as “Standard Windows Icons”. The menu also has the “Saved Icons” bookmark with all icons stored with the toolbar. To save an icon with toolbar, enable the “Save icon with toolbar” option. True Launch Bar will copy the file to the toolbar folder. If the folder already contains a file with that name, True Launch Bar will ask whether it should rename the new file or overwrite the existing file.
Saving icon file with toolbar can be useful for moving the settings between computers and for restoring the settings from backup, since the icons will not depend on the physical location of files on disk.
