Please enable full featured editor for widgets Css

In many Qt projects widgets Css style sheet are essential part of the project. Typically these styles are stored just in MainWindow Ui file. These files can be bloated. Then editing these is night mare. There is no option find nor replace nor bookmarks. Just one (exclusive) Css file edition at the time is another disadvantage. So: please allow normal edition Css files...

I am not sure whether workaround of this "disadvantages" is separate Css file included in qrc file and loaded dynamically for MainWindow?!?
