As I promised - Here comes a pack of 20 different Indicators. 4 Styles, 5 colors of each.
Below are a few steps to change the indicator image,
!Note! To do this we need to change one (1) of the Rocketdocks default files.!Note!
-Close Rocketdock before changing the file-
1 - Go to the downloaded indicators folder and copy/cut the 'X.png' image you want to use.
2 - Go to the main folder of Rocketdock (C:\Program Files\RocketDock\) and then open the folder 'Defaults'.
3 - Open the folder 'DefaultIndicator' (C:\Program Files\RocketDock\Defaults\DefaultIndicator) and change the name of the image file located in this folder (indicator.png), I would suggest changing it to indicatorx.png or indicator1.png or something of the alike. The Rocketdock software will no longer find the file as it only looks for indicator.png.
4 - Paste the 'X.png' that you copied earlier into this folder now and rename it to indicator.png.
