The new form error system is a good improvement to the User Interface as the cause of the errors will be right before the user eyes without any need for hovering.
I have a couple of new additions that will be added to cheetah.
On https://dev2.cheetahwsb.com a new Two-factor authentication system is being tested. It can be set to be required by the admin, but i have that turned off, and i don't really recommend it be required anyway, but i know some will want that option.
To test it, just create an account. Once logged in you can enable 2FA from your account section. You will see a breadcrumb menu item, and quick link, and a section in the account control block.
Also on https://dev12.cheetahwsb.com is a new form error system. The red dots for errors have been mentioned many times in the past and recently it was mentioned again. I did the best i could do without a major rewrite to the entire form generating system. What i came up with should improve things dramatically. Just create an account. Fill out forms with missing required data, ect to trigger a error and watch what happens when you try to summit a form with errors.
