[Ardour-Users] plugin automation editor logarithmic? possible to make it linear?

When I draw automation for a plugin parameter, e.g. the cutoff frequency for LS Filter (from the Steve Harris plugins - see http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html#tth_sEc2.67), the scale of the automation editor is non-linear. This means it is very fiddly to edit automation for the movement of a low-pass filter for example, as the low frequency area has very few vertical pixels ...

Does anyone else see this? Is there a way to fix the issue, or change a particular automation editor to a linear scale?

The issue is exascerbated by the fact that often the "height" for the automation lane changes the above audio lane's height - is this issue being seen by others?

Looking in the XML I see that there are min and max yvalues for AutomationList entries - can these be tweaked to zoom in on a particular range of interest? This would be a very useful feature. Are there any other options than "Absolute" for the "style" attribute? (and related, how advisable is it to go hunting around in the xml like this?)
