Does it give you the information you need when deciding whether to install it?
Are the features and screenshots clear?
Is anything missing?
Nick here from Shopify.
I think the app listing looks good and the screenshots/ features are clear. There are a couple of things I noticed which you could add in to round out the page.
I noticed there was no link to your website under the Support section. If you have a website for GhostApps, I always feel it adds a lot of trust to the app pages if the developer's website is added.
The only other thing I can think off is a video attached in the top right going through what the app is about. Not every app has one and this is more nitpicking if anything, but if you have one it is a great way to find out more about the app in a visual form.
Hope that helps.
All the best, Nick
Without a video|gif, consider using highlights|shading|callouts on areas of the screenshots to tell a clearer story or show a common workflow pain being solved. It kinda does now but it's a lot of UI to take in.
It can be helpful to follow up with previous customers that have left reviews for either video testimonials, use case of what they needed,etc.
Personal nitpick that drives me nuts about apps: update the titles when moving between features and update with relevant info, for example in the current 4th screenshot 'Email PO' becomes 'Email PO#1026'.
When your juggling tabs and tasks context in the nice big titles goes a long way.
