You create the custom pages under the plugins=>custom pages page. You would enter myhome as the route for your page. Then save and go the the extend=>widgets page to add widgets to your page.
Now I just feel the need to create nodebb-plugin-rot26. BRB, trying to mock bcryptjs to provide genSalt and hash functions that do nothing and compare function that just compares two strings
Actually it was an update pushed in the last couple of hours which have solved the issue. At least on one of the plugins which I have tested. I hope it will be the same way on all the plugins. Thanks for your help.
