Improve UI

[jhanca-robotecai]

The UI is quite difficult to use right now. Few minor improvements could help a lot:

• there is no need for "are you sure" when creating a new requester/config (it should be there for removing though)
• when the new requester/config is created, it should be opened automatically so it can be configured
• all options should be opened directly, without a need to open anything, see below
