#884 Automatic Coloring

[Tomophy]

I really want FreeMind to have "Automatic coloring" like "Rainbow" of iThoughts (iPhone app). "Rainbow" is the key to color lines automatically depending on their directions from the root node. The color of each line is automatically determined clockwise as red, orange, yellow, green, blue, indigo, violet.

In addition, it would also be cool if you could the key to set "Automatic layout" and "Automatic coloring" as default on the Preference.

Those features would be so simple but look a bit different than before. It would be cool if those features could be implemented on the next version of FreeMind.
