Features & Improvements Request

similar to things3 I like to have tasks added to a list inherit the tag assigned to the list

It would be great to either change the default tag icon to a different design or allow users to customize it. Ideally, users could choose from preset icons, upload their own, or even use an emoji as the tag icon.

It would be very helpful to allow tags to have a hierarchical structure — for example, being able to nest tags under a parent tag (e.g., Work/Project A, Work/Project B, Personal/Health, etc.).

Would love to be able to change the color of tags

Ability to set the default calendar for tags, so if I set up a task with a tag it will sync back to a specific calendar (like Sunsama does).

I would like to request more filtering options, particularly an option to exclude tasks from projects instead of include them. I have all my "routines" in one project and most of them live in repeating timeslots, so I always go through and check all but this project in my views to clean things up. As I add more projects this becomes more cumbersome.

It would be nice if we have the option to save tag filters so we don't have to keep on filtering tasks by multiple tags and will just have a presaved filters.

We would like the ability to search for tasks using tags within Akiflow.

I've been confused so many times with projects and tags because in ALL other instances on the web and in software, # are used for adding projects, meaning non-exclusive categories where one item is link to many categories make projects with [ or anything else that show it's an exclusive category
