W3 Total Cache Pre-Sales Questions

Hello,
I apologize if this is not the right place to submit pre-sales questions, but I could not find any email address or anywhere else to submit my query. I have the following questions regarding the front-end optimization capabilities of your plugin:

1) Is there a way to automatically remove unused assets/resources (css, javascript, emoji’s, etc.)? And can this be done on a per-template basis?

2) Is there a way to automatically generate and inline critical assets/resources (css, javascript, images, etc.)? Can it be done based on different screen sizes, and can I set the screen dimensions? And can this be done on a per-template basis?

3) Is there a way to use HTTP/2 Push (for critical css/etc. files)?

4) Is there a way to specify whether a css/javascript file should be loaded in a render-blocking or non-render-blocking way?

5) For combining css & javascript files, is the order of the files maintained according to the order of appearance in the html document? This is very important to prevent breaking functionality or styles when combining files.

6) For combining css & javascript files, can I set the locations in the html document where I want to place the css & javascript file links? For example, my understanding is that css should be placed in the html header and javascript should be placed at the very end/bottom of the html body. Can I do this with the combined css & javascript files that are generated by the plugin?

7) If I have multiple css or javascript files, can I specify the order in which they are placed in the html document? For example, if I have one critical css file and one non-critical css file, can I place them both in the html header and specify that the critical file appears first and then the non-critical file second?

8) If css &/or javascript are modified (e.g. when modifying my site with a page builder or gutenberg), are the combined css & javascript files updated automatically, or do I have to re-combine files manually?

9) Is there a way to use “defer” and “async” for loading of css & javascript? Can I specify in which order css and javascript should be loaded, i.e. load all css first and then load all javascript?

10) Is there a way to lazy load media?

11) Is there a way to do progressive rendering of media?

12) Is there a way to locally host font files?

13) Is there a way to combine font files?

14) Is there a way to use thumbnails for videos?

15) Can all of the above features be implemented/different on a per-template-file basis?

16) Have the above features been tested for compatibility with astra theme pro, elementor page & theme builder pro, and gutenberg?

I look forward to your clarifications.
Thanks and Best Regards,
Sal
