OK here's what I'm implementing (feedback appreciated):

Changes for Perspective and Camera views - no changes for all others:

In Arc-Rotate:

LMB: Rotates in various ways.  POI does not change. (No change)
MMB: Click inside the circle dollies in and out.  POI does not change. (Change)
MMB: Click outside the circle zooms in and out.  POI does not change. (Change)
RMB: Click inside the circle moves the camera sideways.  POI moves along with camera. (No change)
RMB: Click outside the circle moved the camera towards or away from the POI and the POI moves along with it. (No change)

Mouse Wheel:

Dolly towards or away from the POI. (Change)

Note: There is no true PAN where the viewpoint spins around but doesn't move. I'm working on getting that in as well (i.e. if the <Ctrl> key is pressed).

I hadn't realized how useful this would be until I implemented it - so thanks for keeping on reminding me about it until I finally did something :)

Not sure I'll fully understand how this will all work but I'm definitely excited to see these changes in action. I've wanted changes to the arc rotate system for years even though I struggle to explain how. I just know It takes me too long to navigate environments in anim8or. To be able to dolly and rotate more efficiently would be a big improvement.

Defineately some interesting changes. Am sure it will be an improvement.
Its a funny thing tho, since year one, using arc rotate in perspective mode caused some pretty strange views, so i've always kept away from that.
 And using arc rotate in camera mode, well, i always thought that was a no-no...lol.
 So, learn something every day....

Yeah, using perspective view is a necessary evil for doing indoor stuff, otherwise you never get to see whats going on inside it unless its a wireframe, or you hide entire walls/ceilings. It takes a lot of practice to use effectively. What I find myself doing a lot is selecting clusters of objects that are big, but not entire room big. and then framing that so there isn't too much distortion going on while using arc rotate.

Edit: Just to elaborate further, the size of what you frame plays a huge role in all this. If the object you select to frame is, say, a door knob, you'll get an extremely distorted view in perspective mode. If you select the entire room, it'll be hard to move around inside it, not to mention it'll look a lot flatter than it needs to. Almost like a telephoto lens. Even though you can zoom in/out after framing, the center point stays the same so this wont help you much. So you need to select things inside the room. If you have a lot of smaller objects, just make sure you're selecting more than one to cover more area, then frame than in perspective view.

Thats really interesting Kyle, and a big help.
 Thanks for that.
It never occured to me to go to perspective view to get inside.......slap forehead...
 
 Have just tried it, certainly better than trying to look through windows, or straining to see bones  through a heavy wireframe...lol
 (or hiding stuff, and anim8ing a character inside to interact with 'invisible/hidden' objects.)

I'll keep this in mind and start using this view a lot in scene mode, me thinks.
 Thanks again.

Steve.
 Bug?. Arc Rotate does nothing in 'other camera views' ?

Edit: Kyle re your edit in last post.
 Ok, cool. Nice one. Thanks. Cheers.

I'm fixing arc-rotate for camera and spotlight views, also the mouse wheel. You'll be able to dolly (arc-rotate center circle, normal mouse wheel) and zoom (Arc-rotate outside of circle or <Ctrl>+inside circle, and <Ctrl>+mouse wheel).

There are a few complications.  It's different when the camera is automatically following a target - then the dollying (dolling???) works more or less as expected. But the POI isn't defined as cleanly otherwise. Currently you can type F to center the camera and set the POI but it's not set as a key.  Once I've posted everything you can help me decide how to handle this.

New build should be out soon ...

Build 1159 was just posted with this added. It's slightly different that my original post (differences in italics):

Changes for Perspective, Camera and Spotlight views - no changes for all others:

In Arc-Rotate:

LMB: Rotates in various ways.  POI does not change. (No change)
MMB: Dollies in and out.  POI does not change. (Change)
MMB with <Ctrl> key pressed: zooms in and out.  POI does not change. (Change)
RMB: Click inside the circle moves the camera sideways.  POI moves along with camera. (No change)
RMB: Click outside the circle moved the camera towards or away from the POI and the POI moves along with it. (No change)

Mouse Wheel:

Dolly towards or away from the POI.   POI does not change.  (Change)
<Ctrl> key pressed: zooms in and out.  POI does not change. (Change)


Note: There is no true PAN where the viewpoint spins around but doesn't move. I'm working on getting that in as well (i.e. with the LMB if the <Ctrl> key is pressed).

Check it out!

MMB with or without Ctrl still zooms in perspective mode in arc-rotate (FOV info in the status bar). The wheel, however, dollies (distance from POI info in the status bar).
