NOTE: The wp-admin interface for this plugin still needs some sprucing up. 
I (blobaugh) no longer have access to Windows Azure to continue improvement. If you need this plugin consider contributing to it, or getting me another Windows Azure subscription to continue development.
The Windows Azure cloud platform provides some very powerful scaling ability, 
however natively Windows Azure does not know how to scale applications. 
This plugin teaches WordPress how to scale your website on the Windows Azure 
platform and take advantage of the full power of the cloud.

This tiny plugin adds silently the viewport meta tag with zooming permission to allow your users to zoom in your website with mobile browsers.
If you find yourself in trouble not to be allowed to zoom with your favourite smartphone in your theme, you can take this tiny plugin just to get the shiny magic zooming with your smartphone in your theme.
There are themes which are “responsive”. But a few of them are cruel. They do not let you zoom in-to your theme.
Don’t be upset, don’t get in panic, don’t spend a lot of money. Allow mobile zooming definitely in your theme.
You just download this plugin and click to activate it. No options page, no settings. Just your theme.
This plugin does all the magic for you and your users zooming with your smartphone in your theme.
Instead, just adding a second viewport meta line in the header section of a page, I started with version 1.5.0 to add theme specific viewport replacement, if available. 
If you know theme which allows changes in the viewport by a filter, please write a comment in the <a href="https://wordpress.org/support/plugin/definitely-allow-mobile-zooming" rel="ugc">WordPress forum</a> and I will add the specific filter.
If you find yourself in trouble with this tiny plugin, don’t hesitate to ask for <a href="https://wordpress.org/support/plugin/definitely-allow-mobile-zooming" rel="ugc">support</a>.
Try it out on your free dummy site and <a href="https://demo.tastewp.com/definitely-allow-mobile-zooming" rel="nofollow ugc">click here</a>.
The plugin does not collect any personal data, so it is ready for EU General Data Protection Regulation (GDPR) compliance. In your theme.
