New this build: a new Z order bar, and better management for third party plugins, behaviors and effects!
Z order bar
A common request has been to have more fine-grained control over which objects appear in front of others. Typically the editor has only allowed Send to front and Send to back. To improve this, the new Z order bar displays the objects in the layout in their complete Z order, and allows you to easily drag and drop them in front or behind other objects, or even to different layers. Note this is a new license-only feature, and is not available in the Free edition.
A neat feature of the Z Order bar is if you select some objects, it only shows those objects and the objects touching them. That means you don't have to wade through hundreds of unrelated objects in your layout which would make it harder to see the Z Order of just a few objects. In the above image, the player spaceship from Space Blaster was selected, and it filters what was a huge list down to just the three objects it's touching.
To add a little extra control at runtime, there's also a new Move to object Z ordering action. This also allows you to dynamically Z order objects behind or in front of other objects, rather than just sending to front/back.
Third party addon developers now have the ability to wrap their addons in a single ".c2addon" file, which can then be drag-and-dropped in to the Construct 2 window. C2 will then prompt you to install the addon. This simplifies the process and removes the need to copy files to the right place in the install directory manually.
On top of that, Construct 2 now also copies installed addons to, and loads addons from, the AppData folder (%appdata%\Construct2). This means if you reinstall or update Construct 2, it should preserve all your plugins, since they're still present in the AppData folder even if they're missing from the install folder. (Note addons are loaded from the install directory first, so addons there take precedence over those in AppData). Also note this means if you want to delete an addon you must delete it from both places or Construct 2 will continue to find and load it. I'll be posting more info for addon developers shortly about how to make a .c2addon package to simplify plugin distribution.
If you use Construct 2 portably, you may still want to copy the files directly to the install directory so your addons get taken with you. (Construct 2 will try to copy addons to the install directory for you, but it may not always have permission to write to the Program Files directory, so you might still need to do it from Windows Explorer.) Alternatively, just take a folder with all your .c2addon files with you. They can all be dragged and dropped in to the Construct 2 window at the same time to install all of them.
