Hello.
What about modified_on field? I change data by your software, but modified_on fields not modifed. And HTTP request Last-Modified not correct! So I have problem with browser cache and with search bots
Ok, that is true. We will add that as optional so user would be able to enable it on in next update. Some of users actuality prefer opposite.
You can also use UDF add-on to edit modified-on explicitly.
