Other fixes

Umajin 3.1

The release of Umajin 3.1 brings with it our new multi-user editing feature.  You can now collaborate with your colleagues directly within the Umajin Editor.


The multi-user system allows people to work simultaneously on the same project.  A list of users who are currently logged in to the project is displayed in the top right corner of the Umajin Editor.  Any time a project member makes a change to components on a page, these changes are immediately (in real-time) synchronized with the other team members.  To make use of this system simply update your Umajin Editor to version 3.1 and it will be available.

Umajin 3.0

This major release sees a move to simplified naming of our applications.  Umajin App Creator becomes Umajin Editor and Umajin Preview becomes Umajin Editor Lite to reflect the new functions within. A totally new User Interface design and all the features below round out this 3.0 release.

Umajin Editor (formerly Umajin App Creator)

We have gone through the whole application and updated the user interface design of our Umajin Editor to look better on higher resolution displays.  The design has then followed on to our Umajin Editor Lite as well.  All component and action icons have been updated as well to give a more cohesive experience.  There is a project history tab in the Project List so authors can see what has been completed on their project and the list is searchable.  You can now drag ‘n’ drop components on the scene tree and in the actions lists in the properties inspector. Guide-wire positions can also be precisely set by clicking on the Guide-wire tab.  Project settings can now be edited in the Properties Inspector and can be undone.

Umajin Editor Lite (formerly Umajin Preview)

The Umajin Editor Lite has had the aforementioned User Interface redesign and we have replaced the old iconic state information with more readable ‘plain English’ descriptions of the projects state on the device.  It includes information about whether the project is loaded, needs to be downloaded, is up-to-date, etc.  Other new features include a new commenting system (which synchronizes with Umajin Editor), console window and pages list screen.  The threaded commenting system allows users of the Umajin Editor Lite to give feedback to the author on specific pages of the project.  These comments can be accessed by the Umajin Editor on the desktop for discussion.  The console window shows information (from the Umajin JavaScript engine) to help the author view state and error information from their scripts and custom components directly on the mobile device.  The pages list shows all pages of the project so the user can find and comment on them even when the page is not navigable.

Notch Support in Android and iOS

The Umajin ecosystem now has notch support on iOS (for iPhone X and later) and Android 9.0 (Pie) devices that have a notch.  The status bar can also now be displayed while a project is active as well.


Google Maps now work on desktop (macOS and Windows).  This will help with testing maps when authoring new projects. We have improved zoom capabilities and the ability to add a fake user location for testing as well.

Numerous other enhancements

We have updated the permissions systems for both Android and iOS.  The Windows Editor is now a 64bit application and we have added macOS Mojave permissions for Camera and Microphone.  There is better management of Text entry components.  The reliability and consistency of feed components has been improved and many other minor bugs have been resolved.
