offer user created 'theme' button for 'context view switching'. So view mode based on link-colors or relationship
Offer the user to define existing link types as 'relationship / theme' links. This makes it possible to discover / visualise different relation structures that can exist all in the same brain. (all un visible or fixed now one and the same brain). The result is that from only one brain, the creator can now select and highlight relationships hidden in a complex brain. So 1 single brain can visualise more stories just by selecting and visualising the specific relationship, and all non-relevant thoughts for that specific relation dissapear to the background.
Context / relationship or Theme switching so to speak.
