This is not possible yet. For the alert function, we did made a JS API : showAboutDialog() function. We don't have a built-in function for user-input yet.

Fixed with a minor update. You can now download v4.0.1 installer from download page.

For the moment, you can ask support at https://websitetoapk.com/support/submit_ticket

We will be adding info on each term in the documentation asap.

@Ubuntu508 Both issues were already fixed as instant updates. You might need to re-download the fixed copy of installer.

Simply download from the website and install.

Material Design is available with latest version v4.0. It allows you to choose suitable color scheme which also applies to your status bar color.

Pull to Refresh feature is now available with latest version v4.0.

@Comdag.Andreas We always work towards making it better and available to more and more users.The real min-sdk-version is set to 14 in the apps, which does not affect any high end devices, it ensures only lower-end device compatibility.

Further, as you said about .webapp project, I would like to request you raise a support ticket, we will ensure fixing the same asap within a day if possible, as we did for each of complaint that we received through any channel. We do ask to raise support ticket as it ensures ticket closes after resolving the issue.

@jfk80 Did you updated to latest version of installer?
