Equalizer can be opened several times
Environment
- Lollypop version: master (20190314)
- GTK+ version: 3.24.5
- Operating system: openSUSE Tumbleweed (20190312)
Bug
Steps:
- Click on the Equalizer button in the menu => Equalizer opens.
- Make some changes in equalizer.
- Click on the Equalizer button in the menu => Nothing seems to have changed.
- Make some changes in equalizer.
- Use go back button.
Result:
Equalizer is still opened but with configuration entered in step 2.
Expected result:
Go back to the main menu. Maybe the equalizer button should be greyed out in menu when equalizer is already opened?
