What is the current behavior?

Issue Number: #168

What is the new behavior?

The form helpers as shown on the stub form can be presented in a large list instead of a collapsable accordion. You should be able to filter the stub helpers.

New stub form helper list with filter

In dark mode, the "response body" form helper form is still white.

Fix sidemenu so you can click on the whole menu item instead of only on the text.

In dark mode, you can barely make out the difference between an enabled and disabled stub.

I added the "(disabled)" text again, just like in the "old" UI.

After saving a stub, a redirect to the stub form with the added stub ID should be done.

Make a difference between updating a new and existing stub. Right now, when you update the ID of an existing stub, a new stub will be added and the stub with the old ID still exists. Add a separate button for updating a stub so the old stub will be deleted.

When you are in "new stub" mode, only the "Save" button will be shown which always adds the stub (of course). When you are in "update stub" mode, the "Save" button will call the "update" endpoint, which means when you update the stub ID, the stub with the old ID will not remain. If you want to do some kind of batch adding through the stub form, you can press the "Save as new stub" option, so that when you update the stub ID, the stub with the old ID will remain.

Checkboxes should also be dark in dark mode.
