HalfLife: half-life maps saved in q1 map format are not supported - currently have to convert them to hammer map format using hammer editor. And vice versa.
Entity: creating a new entity with all the brushes of another entity selected results in the latter entity having no brushes.
SConscript: build fails if SETUP=1
+SConscript: svn.py fails if not using C locale - set LC_ALL?
GUI: can't use arrow keys to navigate in camera view when capslock is enabled
GUI: screensaver causes: gdkgc-win32.c: line 905 (gdk_win32_hdc_get): assertion failed: (win32_gc->hdc == NULL)
Entity: option to filter non-world entities (e.g. not func_group or func_static)
Rotate Tool: if more than one object is selected, with different local orientations, use parent-space rotation pivot instead of local-space
-Texture Browser: add a way to make large texture sets more manageable - shaderlist.txt was previously used this way
Brush: MMB+ctrl to paint texture on whole brush/patch.
Camera: add alternative highlighting styles (used to be J).
Doom3: filter func_splinemovers
Selection: Add optional screen-relative control for constrained rotations.
Clipper: Change selection/manipulation to be consistent with other component editing.
Filtering: Either deselect filtered nodes, or render filtered nodes that are selected.
-Camera: Strafe while holding ctrl.
Texdef: Make texdef formats abstract, add conversion between texdef formats (use generic affine-texture-matrix format for conversions).
Textures Window: Precise display of texture size when selecting. (tooltip, possibly)
Status: 'Size of brush' display on status bar.
