Shared step is one of critical thing while creating tests but there are few things which should be must have in shared steps:

passing variables in the shared steps so that we can have dynamic shared step instead of static shared step.

ability to group some shared steps in folders. Having folder structure will help in organizing the shared steps. This is useful when we have many shared steps

Importing & exporting shared steps from one project to another.

Having child steps in shared step

Ability to view test cases linked with the shared step

Also add a folder structure for Shared Steps. ie. Navigation folder would group all the Navigation Shared Steps
