Hi,
I wrote a plugin for personal use at the moment for project management within Obsidian. So far, I spent time on a proper timeline. Here is a screenshot:
Each project is a markdown file anywhere in the vault, with a “project” property. It can use either tables, or tasks for items in the project list. Timeline has full scrolling and zoom capabilities. Tasks on the timeline can be moved and resized, which updates the data in the file. So project planning can be done purely in the timeline view.
I have other views that provide overall project progress.
Im interested in feature ideas, also if this is of interest to others to release as a community plugin.
Any feedback is welcome

We don’t see the left side or the beginning of this timeline, but most projects go through some phases, which are also seen on a timeline (usually colored differently). Those phases are divided into tasks and then presented with individual MD files.
I love the idea of moving and expanding time windows on the timeline, and it’s automatically reflected in the original file! It’s usually good to write down why you changed the dates—maybe some pop-up or opening this file after changes to the timeline- to give you a chance to write it down.
It would be nice if hovering a mouse over the “blue square” would show a preview or a dedicated short note of the note.
Different “textures” of the colours can show the task status: done, in progress, waiting, …
Worth making a community plugin!
Wishing you good luck … cheers, Marko

I agree, make available, we can take it for a spin and let you know how it feels.
If you set it up on Github, we can use BRAT to give you feedback.
