I am disappointed by the removal of custom options for exporting video in SketchUp 2013. I previously exported in 1920x1080 at 30fps, but I need to export at 3840x2160 at 30fps and downsize later because I'm getting moire patterns in this version. Because I can not use 24fps video, I am forced to wait for Vray 1.6 to come out in August, which is less expensive as a student than upgrading to SketchUp pro. I'm sure there is a valid reason for the removal of the feature, but I would have appreciated a note on the download page along the lines of "Certain options including... are no longer available in this (unpaid) version of Sketchup (after the trial period)."
With that said, I do enjoy the increased stability of SketchUp 2013. I have several extremely complex models that would previously cause the program to crash while doing minor tasks such as changing tools. Thankfully, I have had very few problems not caused by complex tasks.
My recommendations for the 2014 version after hyper-threading and multi-core support would be a way to export with soft shadows. Although that would probably require a lot of work, it would be a welcomed addition to shadow settings for quick visualizations without using a 3rd party software. Another idea is an addition to the warehouse where tutorials of various skill levels are grouped. The type of tutorial I would imagine is a scene with uncut boards followed by a slide of cut wood then another with parts combined until the last scene is a complete project. It could even be used as supplemental visual aid in addition to online directions in any language, just "click here to download a step by step model of how your project should look at these stages." Being a widely accessible 3D software, perhaps a code could come with products that require assembly on the packaged directions.
