LFG VS FlowLine2

I did just for myself, but open sourced it: https://github.com/bjarneo/LFG

It took me years to realize that the most difficult thing is actually to systematically derive what to do, and that in any decently complex project systems engineering (an art and science apparently long forgotten) methods are the only way to derive that in a sufficiently reliable way. The result is - no wonder - not just a gantt chart, but an n-dimensional model with multiple levels of detail. The PMI writings just tell you that you e.g. have to create a WBS, but they leave you all alone with how to derive something like this systematically. Accordingly, the many PM tools seem helpless to me, where some computer scientists have simply built something that corresponds to the outward appearance of what they assume under PM.

I worked for many years on large, complex government projects and eventually started building prototypes for tools that would be useful (e.g. https://github.com/rochus-keller/FlowLine2 or https://github.com/rochus-keller/WorkTree); but you would have to invest a lot more development resources, and whether people would understand the tools and their usefulness (so there would be a market) is questionable.

Transclusion is a very good idea from my point of view. I saw and used it in Ivar Jacobson's Objectory tool and eventually also implemented it in my CrossLine and other tools (see https://github.com/rochus-keller/CrossLine, https://github.com/rochus-keller/FlowLine2/, etc.).
