It allows you to create your product/items list (order list). Usually it looks like list with product description, and image. And basically you can do anything you want with it. We plan to create 3 examples first: restaurant, Changelly alike exchange website and homepage/blog with just embedded code block. So, yes you will be able to setup gofundme style or donation page with it. Backend is api itself, current administrator interface is quite raw, and will be redesigned (check screenshots) but it already have basic functional that allows you to add your products, and see order requests. We want integrate is with sparrow (thats metamask fork) and metamask first. Currently our team is only developers, but I don't think this is the bad thing. Its just makes no sense to show cute renders or somethings else, when we have only prototypes, mostly. And, yes you can just check documentation and test, what we currently have yourself. Also, we want to make frontend as much user-friendly as it could be for novice developers, so its not worth to make it too complex. And yes, beside it could look totally different, with different example (use case). For example when you take popular e-commerce solution, you usually need to deal with very hard in maintenance system. But here, we want to make fast and easy to understand and improve api. That you could use with any website, design or whatsoever, and you don't need to deal with your e-commerce solution, but just make website the way you want.
And as for android client its just reads your products/items and displays your list. And since android client will be open-sourced too, and its in out main priority, it will not be so hard to fork it and create your own clients, specially for your own marketplace with own design, for example.

is there going to be a masternode option?

There will be no ICO. It was bad idea with an ICO from the start. Obviously we can't compete with other start-ups that could spend  thousands on marketing every month. However this is not means the project is closed. Just we going to go slower. With quality over speed. I think as founder in two years I'll be able to run full-time team on my own funds. However, we will continue part-time, as I'll be able to spend extra, and more people will be involved. Meanwhile I want to continue project and help $MUSIC development, since I invested too deeply in  $MUSIC that i was not able to withdraw funds back without huge lose. to spend funds on the marketing. So we will continue without marketing funds right now, and without ICO, but a lot more slower. Main priority is whitepaper and naming conversion service, that will be available soon.

Main priority is whitepaper and special service that can make step in making payment with any cryptocurrency (including bitcoin) a lot easier. I want it released in sync, so there will be no time for any kind of airdrops in next months. It might be, there will be no token at all, we looking into it. Payment system could be profitable without it. We just give interface to pay easy in any already made crypto-currency.

Whitepaper is work in the progress. More above it will be not cool to release even draft without making basic help service that will be part of the Melima project or used as help service or as database for another cryptocurrency payment service, since it will used as example in whitepaper.
