Here is beta.aa
It has various adjustments -
Further revisions to the html MAC version to get the dialog to do its 'populate' at the correct time.
CSS for MAC fonts improved, with dialog fonts etc adjusted to be more cross-platform friendly. MAC users particularly - please try dialogs and feedback - there should be no scroll bars in the dialog now - also check for the 'defaulting' of check-boxes issue
In addition to 'Geometry', Groups & Component-Instances the SKP's 'Images' are now exported. This should address reports of "things missing" when exporting - it seems that this was due to somethings being 'Images' [e.g. logos or a tree's leaves] - a special sub-set of a definition that holds a rectangular image - so now 'Images' will export successfully - note that their material and its texture will be called 'Image1', 'Image2' etc rather than an image-file's 'name' such as 'logo[.png]' - as this is the way Sketchup's API must export them.
All users should upgrade to this version.
Feedback please...
I suspect that there is still fine-tuning to do to the MAC version
