Do not use a modal for entering WIFI passwords
At the moment when the user needs to input a WIFI password the form is presented inside a modal.
This behavior is inconvenient for these reasons.
Firstly it blocks other actions, making impossible for example to copy and paste a password after the dialog is shown and secondly it obscures any view of what is behind of it making impossible to read a note of the password behind the dialog.
I do agree that the current version is visually pleasing and it helps the user to focus on the action but it does not allow any other actions while the dialog is present.
In contrast with other operative systems and desktop environments.
KDE and Windows 10 integrates it on the try menu.
MacOS shows a window that always stays on top of the others, can be moved and does not obscure what is behind.
