TImeline navigation

Dear Toonboom

I find the timeline and its navigation options very limited.
Is it possible to make these following requests for improvement:

*Zoom while holding the zoom key like in the camera view.

*Zoom in on current timeline position/frame.

*don’t limit the available view. I can only see up to 300 frames on my screen at a time. But I want to see the whole scene.

*when moving frames around it is a very tedious process.
After you select and move them once, the next time the selection indicator is only showing one layer, not all the sub layers.

*Make a command area, where you can write a certain action like in Autodesk Maya: “+=100” (then you can easily push the whole selection with a hundred frames etc.)

Is there any updates on this topic?
Cheers, Troels
