Introduce opacity preferences for the dock in overview

The dash usually has a light grey background, but with this extension, it's fully transparent. I think a semi-transparent background would look better. If this is intentional, I've also noticed that the background isn't restored after the extension is disabled.

Thanks :)
I just fixed the bug when disabling the extension!

I will think about adding this feature to preferences, although it is becoming harder and harder to add preferences with gtk4...
If you want to change this for your installation (before I add this to the prefs), you can change the css string of line 19 of dash.js to something like background-color:rgba(0,0,0,0.5) for example!

Alright, thanks. Looks better now, I went with rgba(0,0,0,0.25), which looks like this with my wallpaper:

I agree that it looks cooler :)
I will really try to add this to the preferences, I guess it is really important!

Done, you can test it on last version from github :)
Also changed folder background, as it looked very dark

Thanks, both the dash and folders look nice now and the option to control the opacity works perfectly on my system as well

Cool, glad it please you :)
