Nope, not currently, sorry. Nexus has it's own set of system stat docklets (modules): CPU Meter, Net In and Out Meters and a RAM Meter. Many more are scheduled to be added once the final version of Winstep Xtreme (currently in beta) with the new User Interface and multi language support has been released.
The native Modules/Docklets in Winstep applications also feature the same attention to detail Winstep is well-known for: for instance, the Net Meter modules also allow you to monitor which applications are using your LAN connection, which port they are connected to, kill unwanted connections, etc..., and can also show you a mind boggling array of TCP/UDP stats regarding each Network Interface Card.
The clock module is not only able to show you the time in analog or digital formats, as it is also able to synch your system time to the Internet Atomic Time servers *and* tell you the current time in plain English (male and female voices available).
The Desktop versions of the CPU and RAM meters (only available in Winstep Xtreme, sorry) are also able to show you at a glance which applications are using the most CPU and RAM at that point in time, etc...
You can expect the same level of features and attention to detail from future Winstep modules.
Thanks very much for your informative answer.
Looks like there are already very cool docklets!
If I may suggest, as a humble developer of few SysStats docklets, it's nice to have CPU/RAM/Virtual Memory in one docklet (virtual memory is also an important factor for performance). I also suggest Net in & out in one docklet with IP as a bonus (just to save some dock space). Another nice docklet is one that shows HD space for few drives & opens my computer with a click.
Those are all docklets I created (or modified) so I'll personally miss them.
I'll also miss my beloved MoonPhase docklet.
Anyway, I must say, this dock looks like the ultimate winner! Finally live reflection in Windows, amazing set of features & best support that listens to the users ... Thanks for your brilliant work JcRabbit !!!
