Hammer Feature Requests

Features

Drag and drop of map files onto Hammer, to open
Implementation of variable falloff on displacement tools
Simple lighting preview in 3D view
Hammer <-> HL2 compatibility (able to run both simultaneously without any problems)
On this line of thought - Fix up the wc_ commands and developer environment ingame for HL2 <-> Hammer compatibility?
Updated HL2 FGD (some entities that are used in the sample maps aren't in the HL2 FDG, info_light_relative for example)
Option for compile window to retain last known screen position and size.
Icon in Texture browser to indicate custom material.
Ability to Copy material name and path from Texture browser.
Ability to move the camera while editing displacement maps.
Ability to 'play' the map while in hammer.
Ability to see func_monitor previews.
A 'model browser' containing a search field to search for models. If not, at least a 'model search' feature in the model viewer would be nice.
Proper material folder filtering exclusion.
Displacement verticies editable or viewable in orthographic views.
This goes into the 'going beyond hammer' but make hammer more like UED, in that hammer could be turned into more of an IDE than just a level editor.

Long file names can't be seen in Face Edit dialog.
Face Edit dialog loses focus when cursor moves off the dialog.
Hammer crashes if you startup a game without minimizing it and then reopening it before the game opens.
Point At... button for angle keyvalues only set "angles" keyvalue.
