I'm a bit late in taking note of this – ArtRage 4 released back in February. Look, ArtRage is the best value you are going for a painting program you are going to get on Windows or Mac (it runs on both). I've been recommending it for years, and ArtRage 4,0 still my top pick.
From a feature perspective there are a couple of nice improvements since ArtRage 3.5.5 but nothing major. Having said that let's look more closely.
The Application icon has received a minor tweak. The screenshot below is from the Windows 8 Start Screen with ArtRage Studio Pro 3.5.5 on the left and ArtRage 4 on the right. Apparently they've dropped the “Studio Pro” from the name.
Overall Application: ArtRage Studio Pro 3.5.5
Overall Application: ArtRage 4
The overall interface hasn't changed. You may notice though that some icons look a bit different.
However ArtRage 4 does have a special interface activated via View > Workbench Mode
The Workbench Mode is a minimal interface with a thin strip of tools at the top.
You can access all the brushes by click on the crush icon.
Clicking on color square yields special color picker.
I was already very please with ArtRage's minimal UI and easy-to-access fullscreen mode, so this Workbench Mode isn't that interesting to me.
If you want to see it in action, there's a YouTube video available of someone walking through some more UI changes and new feature
Launching CMD.EXE or PowerShell in a specific folder got MUCH EASIER in Windows 8 thanks to the File Explorers's File Menu.
First open any explorer window. For example below is a folder in my local SkyDrive. Then click on the File menu in the upper left hand corner.
The first think you'll notice is that has a useful frequent places list.
To launch CMD.EXE:
To Launch PowerShell
But be aware of which folder CMD.EXE or PowerShell will be started in.
You can see thay the explorer window is open D:\saveenr\skydrive\Public
If nothing is selected as shown below
Then clicking on File > Open Windows PowerShell will start the PowerShell session in current location (D:\saveenr\skydrive\Public)
However, if something is selected, for example the Visio folder then the PowerShell instance will start in that folder (D:\saveenr\skydrive\Public\Visio)
It even supports multi-select – if multiple folders are selected, then multiple PowerShell instances will be launched
