Hello.
i used to have all the brush options on the right hand menu. now they are gone and only brushes i have used before show up. how do i get them back. thanks

What you call "right-hand menu" probably are the docker palettes shown by default on the right-hand side of the window. Unless you meant the popup palette that appears when you right-click.

See the following topics in the manual:

* https://docs.krita.org/en/user_manual/g ... cepts.html to learn what dockers are
* https://docs.krita.org/en/reference_man ... space.html to learn how to reset the workspace to default
* https://docs.krita.org/en/reference_manual/dockers.html for a list of all the docker palettes that Krita offers. You can show/hide them in the settings->dockers menu
