Hi
Some time ago I created form filler (kind of chrome extension to quickly go through forms in web UI of your app) called Filly (https://fill.ly/). Backend of app was obviously created in Yii2 
Week by week I has been adding new features that may be helpful for developers. All of them are created because I felt I need something like this in my daily work.
So this filler allows you:
- Save demanded form on any webpage - let’s say you build “Add product page” and you have to run it multiple time to verify if everything is ok. You may save basic data about product: name, description and plenty of other fields.
- Restore form state with one hotkey
- Map domain to support many instances of the same app. Let’s say you tested “Add product page” on your myapp.local and now want to check it on stage[dot]myapp[dot]com - if you map domains you’ll automatically have forms shared between different domains.
- Share forms in the team. If you work on the app with other people you can create team, setup common domains and you’ll automatically have everything synchronized.
It’s kind of missing piece between automated tests (which I support with all my heart) and manual clicking which is also necessity.
If you work on any app that has a lot of CRUD-s than I would be more than happy if you use it. Also you can PM if you need more info.
