this is my first addon. with this addon you can link/append objects from other blend-files
i started to write this addon because i work on a bge game where i want to link objects.
it is more than the build-in link/append function. you can select objects in a object-list or sort them by category.
it has a bug at the moment, if you install the addon and safe the user settings, then the list where you can select these objects (see second image) is empty.
at the moment you have to update the list.
i have planned some more features: showing an image of the object in the panel, showing information about the object (some are implemented(see first image), missing: for example license of the object, warnings, used textures.
i also planned a feature to import object-groups, LOD and a random object from a group
it is still in development and the status is like a "test"-status at the moment, but i hope that it will be useful for projects like the project gooseberry too.
