Please correct the "presend" typo in the second sentence. There should be "present" of course, but it seems that I can't edit the post anymore. 

but the one issue that hasn't been fixed yet is a texture shift when moving a brush with UV-lock modified texture scale, while texture lock is enabled. 

start asking for stuff? It's Christmas...

In Tools/Options/General/Window Setup, a checkbox "mouse hover activates window" (enabled when "Use independent window configurations" is checked).

When using independent window config, just passing the mouse over a window would be enough to make it the active MDI child. You already detect which window is under the mouse when we press arrow keys, right? So, just give focus to the window under the mouse.

This way I could use an independent 3 windows setup exactly like the standard single window divided in four. That would free the user from the standard single window setup.

I tried to ask for it before, but it's hard to explain, even worse in English.

P.S.: still looking forward for Volatile Engine :)) 

And still hoping for that sweet, sweet tablet support. Maybe next version. :)

But the sky rendering is bitchin'... 

I have:

- worldspawn "sky" property set to "interstellar_";
- C:/dev/quake/work/markv/id1 is my Base Game Directory (at Tools / Options / Game Profiles / Configuration Settings)
- At C:/dev/quake/work/markv/id1/gfx/env there is interstellar_bk.tga, interstellar_dn.tga, etc., all six 512x512 images;

The skybox doesn't render. I see the scrolling sky texture only. What am I missing? 

2PuLSaR:
Sorry, I forgot about that. Will be fixed in the next release.

2WarrenM:
Same thing, will work on tablet support a bit later. Most likely it will appear in the next version.

2adib:
1) Ok, I've added your request to my todo list. Sounds not too complicated.
2) Skyboxes are currently supported only in Quake2 and Half-Life, where they come out of the box. Quake instead uses a special 2-image texture, and JH uses it to draw cloud layer. If you tell me which custom engine supports skyboxes (and which is the most common), I'll be able to test them and then add to the Quake profile. Additionally, a FGD should also be modified: sky(string) should be replaced with sky(skybox). This means that a FGD for that custom engine should also be included to JH installation. 

1) Yay! Thanks!

2) Sorry, you're right. I misunderstood the description.

I believe that engine would be Quakespasm, the one recommended for the map jams. 

This stuff alone makes this update fantastic. There were a lot of weird bugs and size/positioning problems with the standard hammer curve tool that seem to be fixed here, so yay!

Will test thoroughly over the next few weeks :) 

Is there any documentation for Jackhammer? I can't seem to find it. 

It's basically hammer. So find some hammer docs if you're totally new to this editor.
