Thanks for the feedback, and by all means continue using SketchUp Make as long as you like. We’re still early in the development of SketchUp Free and we have quite a bit of work still left to do. Thanks for giving our new baby a close look.
Performance is difficult to judge, but I assume you’ve come to the conclusion you reached by comparing the performance of SketchUp Make directly against SketchUp Free using the same model, same computer, &etc?
Performance while saving and opening models will depend on your network topology and on your physical proximity to our datacenter. It will always be slower to load a model over a network than it is to open it from your local disk, but we have the ability to take advantage of your local browser cache to manage that latency. Modern cloud infrastructure (we’re using Amazon’s) is pretty amazing at rebalancing itself dynamically to maximize performance.
Of course, if you have exceptionally large/complex models, your experience may vary. And for that reason, we’re keeping our old desktop applications available to everyone in addition to SketchUp Free.
We do support all of SketchUp’s default keyboard shortcuts (some caveats apply: the browser ‘steals’ a couple of them in ways that we can’t yet work around) but maybe what you’re really hoping to see is a system for managing your own custom shortcuts?
