I've tried to apply this patch:
https://bugs.launchpad.net/inkscape/+bug/188381
As you can see, it works, even though I know nothing about patching:

Since there is a working patch available to enable tolerance control from the toolbar, is there any reason why it hasn't been committed? (apart from the fact that tolerance control does not work from the pref window, but if you can access it from the toolbar, there is no reason to modify it from prefs anymore).
This, however: https://bugs.launchpad.net/inkscape/+bug/188849
Gives me errors (mostly ¡®sp_curve_unref¡¯ was not declared in this scope and similar)
Unfortunately I have no experience no the matter. Is anybody else looking into the matter? Better smoothing would be so very welcome.
