Hi Alan Rhodes,
Any object should belong to one specifpic layer, eg. O1-L1, O2-L2....
The links could be in one layer Link-O11_to_O12 and Link-O12_to_O13,
or an interconnection between different layers L1 to L2 like:
Link-O11_to_O21 where O11 is on layer L1 and O21 is on L2.
Short a layer is only an new (unique) attribute of an object (= Thought), and the defaultlayer has the ID = 0 (Home-Layer).
You can define as many layers as you want, only the home-layer is mandatory all others are optional.
Now with tick-boxes you can switch on/off one or more layers. At least you must choose one, if you don't select one, so you will see layer L0.
For example I can show the layers:
L0, L21, L53
if I like... or better need to analyse this point of view.
If I use the expert mode (for example I can switch this on in the customizing properties), I can see not only the selected layers - even I see the "link-ports" to other layers!
I want to see my layers:
L0, L21, L53
with the objects (=Thoughts):
O0.1, O0.2 on layer L0
and aditional I see that O53.1 has and link-port to L66 and L65!
For visualisation reasons I would put the list of layers on the left side of the plain and make a different colorcoding between active/inactive layers (e.g. like 3D push buttons on/off or whatever). So the link-ports-connections to this list can be switched on and of. So I get animated to switch my viewpoint. E.g. I "live my thinking-live in layer3, L3" and I browsing around and run in object O3.1 and I now see that "my" thought is an very old one, which is the same like in this case of the antique thinking in layer L698. Now if I follow this link (expand L698), at first I see my connection to this layer, this means the connections from O3.1 to O698.34 with an link-type "like diogenes" (which I can define).
So I see that my thinking belongs in some cases on different layers, it depends on the topic, or party or hidden interests, whatefer.
Thanks and Regards,
P.S. It it works well, I think it will be very intuitive to use - like on any painting-program (design-tool or webbrower-technology) - and gives lots of new insights with an holistic view of the world of thinking.
