- You need to make it possible to clone an existing template that shows of the features, see Notion as an example of where you almost always start from a template. (I see this is a paid feature maybe, but if so then you need a trial because it's not complete without it)
- When creating a project I'm not likely to know why I would want a label text and color.
- There is a lot of functionality and that makes it hard to make a path through the app (UX flow)
- For some cases, like Software Development estimating the cost/time is hard. Part of the reason that we do Fibonacci story points as a measure of complexity. This isn't going to apply to every type of project, but if I'm modelling out a tech startup using your tool then it's going to be an issue.
- Features, Pricing, Contact Us, How to's should not be in the top menu after I'm in the app.
Overall I think you have a solid problem that you're trying to tackle but it needs to be a lot easier to approach than it is currently. That means making it much easier to add common types of things (if it's a wedding the interface could look quite different, to planning a trip), it's the same mechanics under the hood but I'm not left drowning in options.
As I said in another comment. Congrats on launching.
