When you select an object, the 3ds max interface the lower left corner will display: 1 the Object the Selected
When you edit a polygon, the vertices selected will be displayed in the command bar on the right, such as: 16 Vertices-the Selected

Why not put this information together? When you carry out an operation, the information center can the results of real-time feedback to the user, like Photoshop! and users do not have to worry about due to a scroll command bar but not the select few vertices.

Suggested that the "information center" and I mentioned before, the "selection center" together.

MR is a great renderer but unfortunatelly it has flaws.
What i would really want to see improved are:
1. Support render elements for various MR shaders such as sss skin, car paint etc. Currently they seem completely black in the various render elements such as specular, diffuse etc.
2. Improve the SSS skin shader. It has problems when used in a compound material such as multisubobject, blend, shelac etc.
3. Add more render elemetns such as AO, the ability to render the parti volume as an render element etc.
4. Make various render elements such as mat id, object id, ambient oclusion be transparency aware. If a use a cutout map on a material to make some areas of an object transparent i DON'T want them to be included in the material or object id pass, or the AO pass.
5. Make MR more compatible with max in general so that varous plugins may become compatible with it.
6. Make MR more compatible with hair & fur so that it interprets it as the scanline or other renderers do. Currently, MR usses the hair as a MR primitive when calculating shadows and reflections and refractions (even wen the hair is rendered as a buffer effect). This makes it VERY time consuming.

If you single tap a key, one action is done.
If you double tap it within a narrow window of time it triggers another action.
This would allow people to double up on custom binds and group similar tasks together.

Examples:
- Single Tap: selects the move tool. Double Tap: brings up the Move Type In Transform tool.
- Single Tap: weld. Double Tap: target weld.
- Single Tap: cut. Double Tap: slice.
- Single Tap: selects bridge. Double Tap: Brings up the bridge caddy.
- Single Tap: selects move. Double Tap: Cycles the gizmo between local, view and screen.

I wrote a maxscript that tackles this issue but it's cumbersome to write all the necessary scripts and not everyone is willing to invest the time and knowledge to set it up even if it will save them a lot of time and streamline their workflow.

Note, the script that I wrote the double tap function cycles the move gizmo between local and view. It could be expanded so basically a single key can control a list of commands and to cycle to the next command you double tap. If you single tap it does the currently selected function.

If you really wanted to make it useful, double tap could be set to pop up a visual list that would fade out after a few seconds. The list would highlight the currently selected item and pressing the key again would cycle to the next, double tap again would apply that command. So its basically a command browser under a single key.

This would eliminate a lot of finger twisting key binds that people have to make like "ctrl-alt-shift-p" just to get a unique bind.

The script that I wrote:http://dl.dropbox.com/u/2336353/VigTools-ToggleMove.ms
To install: Run it once from anywhere, bind it under the Customize UI menu.
What it does: Single Tap: selects the move tool. Double Tap: cycles the reference coordinate system between local and view.

3ds max 2012(nitrous mode)
3ds max 2013(nitrous and d3d mode)

In these releases hiding objects no longer benefits viewport performance.
What is worse hidden objects completely kill animation playback performance since everything gets reevaluated every single frame whether or not it has anything to do with the animation, is hidden or is disabled.

This means having things such as hair & fur for a character in the same file as the character itself (which I'd say is the first instinct of any character artist) is nearly impossible because it is weighing too heavy on these versions of max.

Bring back the old functionality of hiding things that would rid the viewport and playback of the unnecessary overhead, personally i would value a simple thing like that over any of the features introduced in the last few years.
