I'm not talking about kanban boards or "issue spreadsheets" (the new github projects feature), but more of something that you could show to the board of the directors as well as publish for the end users, like a one- or two-page presentation with defined high-level milestones.
I tried Notion, but it does not cut it in a sense a good-enough result requires too much of a tweaking.
It would have been nice if I could export features from github/gitlab to such a tool, group them by similarities or single out the bullet points and then rearrange in a visually-appealing manner.
Do it manually
Excel
Lots of neat templates and easier to build something quickly
One Page Project Manager is a well known and easy to manage method but not very pretty
PowerPoint
Lots of cool templates and examples are available and you can tweak them, add overlays etc easily; better when trying to fit a lot of information on one slide
Draw.io
Takes a while to get used to it but definitely easier to use for lots of graphics it you need it, has a neat set of infographics primitives
