Create coloured markers on top of Maya's native timeline. Comments can be added to each marker that appear as tool tips.
The UI elements are added to the timeline menu and can be accessed by right clicking on the timeline. You have the option to change the color of your marker points and also add comments where necessary. ToolTips will appear to show the comment while hovering over the timeline. The markers are stored in the maya file.
The following functions can be used outside of the ui. Make sure the language is set to python.
