They do read these and periodically collect requests into some internal database.
I personally have made this request in past cycles. So it is already in the database with a number.
The problem is the change is not trivial. It is mixed into SketchUp’s locale language handling. (Hence the reason that templates are currently located down in the “Resources” folder hierarchy.)
There are internal strings (“name” and “description”) saved into the file header, that are language localized for templates. These are the strings that appear in the Template selection dialogs (Welcome panel or Preference dialog.)
A new scenario needs to be invented for this string handling. Either all translations (of these two strings) need to be saved within the file somewhere (AttributeDictionary?), or an external translation string file needs to be saved into the “Templates” folder, and all these strings changed over to English “key” strings for lookup into the string translation file(s). The latter I’d expect to share the same base filename as the skp template file.
I did suggest these things in the past when discussing these template issues and features.
FYI, the Mac editions still do not have a Files panel that brings the user folders feature up to parity. But this is a long standing “platform parity” request.
Regarding, a Trimble employee giving a “when some feature” answer, see the standard answer they always give:
Which was also the same when Google owned SketchUp, as it too is a publicly traded company.
All they are allowed to do publicly is acknowledge the request. From time to time some will add a like, or throw in their own 2 cents on a request. But that is it.
