_jm.get_data("freemind") does not seem to return the correct format for freemind or freeplane.
Specifically, the text color and background color do not come over.

jsmind puts them into attributes. I created a mini-mindmap with freemint and colored the text, and that is part of the node.

like

< node COLOR="#ff3333" CREATED="1726129088555" ID="ID_1126999578" MODIFIED="1726129132903" POSITION="right" TEXT="ö,l,öl,l"/>

the blank space above before node is needed in this forum, otherwise the node will not be shown in this issue.
