I could imagine you could have the best of both worlds:
+-+-----+-------------------------+
| | | |
| | | |
| | | |
|A| B | C |
| | | |
| | | |
| | | |
+-+-----+-------------------------+
Where B is the previous level of the tree, C is the detailed table view of the current level, and A is a compressed representation of all the previous levels (you could e.g. click on it to replace B with B's parent, and C would get replaced with details of B).Did anyone try something like this out?
