Item 'Settings' should have an arrow that signifies that the side menu will have another items.
Mainly I think this should be a dropdown menu for Settings (if possible.)
The panel 'General Settings' has a lack of an 'Approval' icon or button (ok) when change general settings.
Widget settings for URL has no feature of change back or arrow back after Custom Domain radio button is checked.
Not really clear why we have Statuses and Categories from the beginning, should add a tip description under the panel header. Mainly there would be very good to have tips here or there.
Developer panel looks ok at first.
Integrations looks very nice
Subscriptions looks a little lack of marketing and better highlight of different plans. I've tried to change my plan to Indie, but this haven't happened, the button was in 'Loading mode' and that's it. Should use white preloader instead of black on the button.
