How can we improve WHMCS?

The UI for WHMCS upgrades is inaccessible. This prevents a screen reader from interacting with the modal window to initiate an automatic update and effectively makes the automatic update feature broken for those users who do not use a mouse. If a confirmation to continue is absolutely necessary, then the modal needs to be accessible without use of a mouse. Alternatively, a checkbox on the upgrade page should be added, the pop up could open a new window, or a new page can be designed for the confirmation and upgrade results.
