I wrote this addon when levelling Foraging - since it was annoying to me to keep checking what the icons on the minimap were.
If you have Docker installed, it will place an icon in the Dock.
If you do not have Docker, it will place an icon somewhere in the topleft of the screen.
The icon is a silver diamond on a minimap style button. The button will initially be gray, and can be moved around by dragging.
Once it is in place, RIGHT CLICK the button, and it will gain some color.
At this point, the configuration screen can be accessed by LEFT CLICKing the button.
This will display the RT Config screen, which lists all Mining/Foraging/Fishing node types.
Use the checkboxes to select which you are interested in seeing notifications for.
At the bottom of the config screen, is a dark red box, showing an arrow, a resource and some text.
Using the mousewheel on this red section will change the size of the font used.
When the configuration screen is visible, there will also be another blue bar shown, labelled 'Resource Tracker'
This is the anchor for where the alerts will appear. This can be moved around by dragging the blue bar.
The arrow will be green or red (red indicates that the node is significantly above or below you)
There may be up to 4 icons above the tracking data - if these are visible it is becuase you are tracking a node type you dont have the corresponding Track buff active for.
There is a a /resourcetracker command option, though it only takes the parameter 'reset' - which is used to reset all UI elements to near the top left of the screen - in case they go missing.
