And yet you are here 
Kidding. I think its a great idea, but if you feel you are missing something with Sitejet on cPanel the best way would be to raise this request with them - they are a different entity and have Sitejet integrated and its probably the best place.
For Sitejet Studio users, you can use 99% of the whole tool for two weeks for free plus we have a dedicated colleague where you can book a one-on-one demo and on top of that an extensive knowledgebase. Is that demo enough? That is the same as Wix, Squarespace, Shopify e.g. offer. Well, at least they offer the free trial…
I think we got it covered, don’t we?
