Better upgrade method
I'd like to request a better update system. The fact that each update comes with a fresh set of templates is holding us back upgrading WHMCS, because we have to restore our custom templates with every update which is an enormous amount of work.
It would be much better if WHMCS would patch (could be done using 'patch' tool) the current templates instead of overwriting them.
Currently WHMCS also restores templates when there has been no modification in the templates. Causing us to restore our custom templates even when there was no change at all. This could also be fixed by patching templates instead of replacing them.
