minor UI suggestion: don't gray out the UI when a dropdown is active
Created by: akhmerov
Right now when the user activates a dropdown menu from the top bar, the rest of the UI is darkened, like this:
I personally find this change distracting: it is large and happens abruptly. If a user is then searching through different menus, the screen blinking becomes also unpleasant.
Darkening of the rest of the UI may be useful when it indicates that the user is in the process of doing something, and may not/should not touch anything else for the process to succeed. This is the case for confirmation dialogs. Another potential use of this darkening of the UI is to draw user's attention to a change that happens at a different place from where the user clicked. This is the case if a sidebar appears when the user clicks on a button somewhere else on the screen.
I think neither use case is relevant to the SciPost top menu: the action of finding a different page is not a process, and the UI changes are local.
Therefore I suggest to not modify the rest of the UI when SciPost expands a menu.
