I recently installed Ubuntu and noticed a possibly purposeful behavior.
If I add "Chrome" (just as an example) to favorites (which pins it to dock), clicking "Show Applications" button does not list Chrome as one of the apps.
If I remove Chrome from favorites, it turns back to "Show Applications" menu. But I like it in dock.
Searching still returns Chrome, and I can start Chrome from dock anyway, but I wonder if there is a way to "Don't hide apps that are favorites"?
