Ubuntu 18.04 UI Not Good

Is it just me or dose the user interface for Ubuntu 18.04 suck?
I’ve been using Ubuntu since ver.9 and never had as much trouble with the UI as I have recently had with ver.18. The new desktop seems unorginized, the app bar wont hide. Also seems to be using more recorses and run slower. Is it just me or are there others who are having the same issues.

Please troubleshoot and file useful bug reports for ‘unorganized’, ‘app bar won’t hide’, and excessive resource usage.

Remember that developers cannot fix problems that they cannot reproduce, so useful bug reports are essential to the health of Ubuntu.

If you need help or training to conduct the troubleshooting or to file a useful bug report, the gurus in our support venues https://community.ubuntu.com/t/finding-help/7121 are happy help.

Closing - bug reports do not belong here. Sorry.
