Showing Translations Validity in a Non-Modular Fashion

[ravage84]

Context:
As mentioned in #811 & #812, validating the translations can be a quite common step for us.
After the validation of the translations, a modal, UI-blocking window for the results appears:

One needs to press "OK" before continuing.

Feature Proposal:
Using other means than a UI-blocking modal window.

For example, the existing "Validate" button could visually or by text indicate the current status of the validation.

Alternatively, some other real estate of the UI could be used for that.

Another option would be to simply use a non-blocking window.

Rationale:
Blocking the UI, especially in non-severe situations is not necessary and not blocking could thus improve UX.
