Anything temporal.Todo tracking. Hepta has todo lists and a daily journal l, Todos aren't treated any differently than other data. Journal is lacking a lot of journal features.Dependency trackingOngoing activity trackingIn short a project is a MOC / whiteboard... no different than any area of interest with very little in the way to time management.Coordination between multiple people. Heptabase offers a nice sharing system but that's it. It encourages an idiosyncratic non-standard way of working which will be difficult for other people to consume.An authoring system. Most good note taking systems have the problem of creating an idiosyncratic system. Many though have tools for export into public forms (Scrivener for book length documents, Ulysses for articles, Dendron a codebase, Zettlr an academic paper...). Heptabase lacks an export authoring system. It would pair wonderfully with most of the systems that do have this (the Obsidian -> Zettlr above would work equally well with Heptabase).Bulk operations. In particular mass document archival and manipulation. There is no easy way to get a lot of information into Heptabase nor any easy way to manipulate it once it is in there. I discussed this in the review. I should mention many PKMS are not good at this, you see these features a lot more in the KMS space (departmental or enterprise knowledge management).On a related note: handling of sound, photos.... is poor you can attach to a note and that's about it.No graph view. Not really needed but it would be nice. I've thought about importing to Obsidian just for the graph.Creative design. Doesn't matter to me but for the very right brained who like to draw...Total information preserving export. This one does worry me a bit. I'm experiencing the pain of partial but pretty good information preservation in moving notes out of VoodooPad.So what I'm doing is pairing with:Work systems / client specifictodo systemOngoing areas where activities and notes are both required. May or may not be in my todo, still deciding.retention / archival systemarea specific solutions (example music).
