 LuxBlend rewrite
 
 Code Design:
-- properties/UI: both easy to script and easy to hook in "special draw functions" for complex UI behaviour
-- node templates (with same requirements as above)
 - no duplicate code for still/animation/viewport
-- caching for still/animation/viewport
+- caching for still/animation/viewport (see https://github.com/LuxCoreRender/BlendLuxCore/issues/59)
+- one luxcore session during animation render, with updates (to avoid kernel compilation times), see issue 59 linked above
 - make viewport render robust (no running in background unwanted)
-- one luxcore session during animation render, with updates (to avoid kernel compilation times)
-- good workarounds for the Blender ID issue (datablock renaming, append/link - maybe wrap with operators)
-- if possible, have properties, UI and export code in one place for each material/tex/...
-- idea for image tex nodes: create blender image tex for each, use its id block
+- Only use new PointerProperty, no more saving the name as StringProperty. 
+  It should be possible for the user to link or append datablocks and have all 
+  required dependent datablocks linked automatically.
 
 Features:
-- find out how to use the same viewport color stuff as Cycles (and/or, if that"s not possible, code something that works... in all possible editors etc.)
-- Texture tab behaviour similar to Cycles (Brush textures, particle textures, modifier textures)
-- help buttons in every Lux panel header (expand to an info text explaining the feature)
-- idea: for lightgroups and every other "fake ID" implemented as strings, 
-  have an update method that searches the whole .blend for "fake IDs" that point to the old name and updates them to the new name. Would require a way to identify these "fake IDs".

+- help buttons in every Lux panel header (expand to an info text explaining the feature) - or just a link to the wiki?
+  In any case, make it so it's not annoying to pro users, maybe add an option in user preferences to disable the buttons
