Hi, every android launcher have a “app info” option when you click a long time on a app, but bliss launcher is missing this option! 
I know you can go to settings > apps > click on the app, but thats not what i want 
But i have another frustration thing: when i uninstall a app, then the shortcut make a blank space. But that problem is also in the stock rom, haha!
Have you ever tried to reset the Bliss Launcher?
> Settings > Apps > Bliss Launcher > Storage > "Clear Data" | "Clear Cache"
This operation removes unwanted “placeholders”.
which info you are searching for ?
block internet, delete cache, etc. All the info are nice to know.
I have just tried on some apps. And the ‘Info’ opens the same site as when you using settings / apps.
So, I’m sorry, can help you with your ‘issue’
