Updates to PHP configurations across multiple virtual servers can be done using mass update feature from List Virtual Servers page (available only in Virtualmin Professional) or using Virtualmin CLI.
I have not installed my Pro yet so I cannot tell you what List Virtual Servers is but I am guessing it is a page you can select checkboxes and perform certain actions.
Further thoughts
Most websites promoting a Pro version usually has a comparrison table and I personally find these very helpful. Also If there are any missing features I cant do a suggestion and get them added to the list.
Most software sellers have a dedicated page, this is also a sales tool.
The shop page is not the right place for feature listing and you cannot list everything. People would not expect a Free/Pro comparison here, it is not logical. People might click on the shop link because there are not that many links in the menu, but not out of a desire to find the difference between the two versions.
The key features page is useful for showing further information of a particular features. Not every Pro feature needs an explanation.
personally I get hacked off with sites like this scrolling down to see all the features, @Ilia 's approach is better for me.To convert this would amount to around 30 rows plus all the other page furniture so a comparison would need scrolling rather than the all on one page as it is currently
Do you suggest a page that lists EVERY single feature of the GPL and Pro version? I honestly believe this being overkill.
People usually don’t jump on the bandwagon buying software if they have the chance to try out free of charge. They download GPL and get teased with the pro features within their installation which allows them to conveniently assess if they need them and throw some money at the devs to purchase the pro version.
IMHO feature comparison pages should list standout (or epic) features, not every little something.
I’m fine with the high-level overview the shop page depicts.
