Here are the things you can do with the Feature Request:

Voting System:
Each feature request allows other clients with access to the same product to vote up or down your suggestion.

Comments:
Talk out the details of a specific feature request by responding to the author and offering your constructive opinion.

Email Preferences:
You can enable or disable email notifications for new comments or status changes to your feature requests.

The features with the most votes will be added in the next version. Please don’t forget to add any features you would like to see added on to the next version. I know you see have seen that some of the modules have not been updated after you have made requests to add new features BUT I can give you my word that each of the modules I have on my site will be updated.

This is only of WHMCS 7.9.x Only
5 - In order for this module to work, WHMCS's AutoAuth feature must be enabled. If you haven't yet enabled AutoAuth previously, edit your WHMCS's configuration.php and add a random $autoauthkey variable, e.g (Make sure you change the string to something random). $autoauthkey = "surheuheruhryeyr8ye";

If you made any custom changes to these templates files you will need to make these changes again inside of the new template file. These templates are based on the default template in 7.x.

Remember: After upgrading, your browser may still display cached versions of the previous files. So if you get any display issues or inconsistencies, always try clearing your cache first, both in your browser, and the WHMCS templates cache (templates_c folder files)
