Google search has become annoying and limited. Previously you could set your settings to exclude websites instead of doing it everytime, you had filters too and it didn't ignore your words in the quotes (you didn't even need those).
Notifications have become quite annoying as well. Every app seems to abuse it in a race to get to the top. I wish there was something like spam notification filter but then again, that would give more power to google to decide what goes on and out.
For some reason they decided that conventional page navigation is old-school and they had to reimplement it in JS (gotta justify front-end developers' salaries I guess).
Of course, the (obvious) outcome is that navigating between YouTube pages is slow as an old pig and the conventional, browser-based navigation was faster (who thought native code with decades of experience and optimisations would be faster than JS?). I now always press F5 to do a full page reload as soon as the address bar updates as it's faster than letting their JS-based crap do it.
