LUMENRT Update 15

I've just spent a couple of hours with LumenRT Update 15 and have a few comments.

First, congratulations to the development team - there are some good improvements. I also tried everything to make it crash - without success.

• screen text;    "Date: [date]"  - this is pre-populated with "1 May 2020" how can this be changed to today's date?

• WEATHER>Aerial - this affects the haziness of the ground plane towards the horizon... but why call it "Aerial" in the context of "WEATHER"? ie. what is "Aerial weather"?

• SUN POSITION> Year. Why have this variable? Looking at the shadows, I can's see any difference in solar position between 10 December 2020 or any other year. It would make sense if it called up the leap-year date options for February, but the calendar offers 31 days for all months anyway.

• Disable clouds shadows. This is a useful feature. I've always run clouds across the sky and paused them to get sunshine in my scene, so this is a valuable improvement. I'd just change the language to "Disable cloud shadows" (singular).

• CAMERA SETTINGS> Use fixed camera height. Nice!

• NAVIGATION OPTIONS> Save window rect  What is this? What does it do? "rect" isn't a word.
• NAVIGATION OPTIONS> Pass through wall Assuming this is intended to prevent navigation through solid vertical objects? It doesn't seem to work.

• ORTHO PROJECTION - still hoping for the ability to render pure plan and elevation views (ie. no camera)
• Birds - still flying around unnaturally, would be better if they flew in flocks (and preferably pigeons, more likely to occur both at the coast an inland)
• Dialog panels - need to undock from their current position at the toolbar. They obscure the view while making adjustments.
• MATERIAL PROPERTIES - it would be good to show all material properties at once, currently cumbersome to scroll through Color> Normal Map> Roughness>Metallic>ambient Occlusion>Displacement>Backlighting.
• EXPORT CLIP "Press Esc to abort"... too easy to inadvertently abort an animation export. I multitask several other apps while rendering and have hit Esc by mistake while exporting a clip. Actually, Esc used to abort the rendering even if LumenRT was not the App in focus, and I see this no longer happens - but it still seems too easy to inadvertently abort (ESC is used for too many things). CTRL-C would be better.
• UNDO should only apply to changes made to the model, or settings. It should not undo view states. This should be a similar principal to the way that Microstation draws a distinction between "Undo" (CTRL-Z) and "View Previous".
• LAYERS still clumsy (defining layers by object with color codes)
• PLANTS thumbnails in the collection are too dark.
