Today I updated to Hesk 2.7.3 + MfH 3.0.7.
I noticed that you introduced a classification of the items under "UI interface colors" settings, ie you split them into:
* Common Properties
* Custom View
* Admin Panel
However I did not see any change in the length of the file text.php (English language) since 3.0.5, so I suspect you forgot to insert these strings as "variables" to localize. Or am I missing something?
Anyway, below I report a screenshot of what I see when that page has the interface in Italian.
A you can see, embedded in red I highlighted the three strings which are still in English.
