I own the G15 keyboard and like to use some of the applets or mods that people gave made heres some of the best ive seen and found. Top 10 in no particular order.

- SirReal’s multipurpose G15 plugin [v2.8.5]
This what im using on mine shows CPU usage, Memory, Time, Date, Internet usage and much more has a small nag box if you don’t want to pay or you can pay to get rid of it in the way of a donation.
- VLC Media Player Control
If you use VLC like me then this will do the job
The link to the VLC applet says I don’t have access to that page…? Any way you could post another link elsewhere?
I updated that link for you.
Hey, is that mod for the calculator still available? The old link doesn’t work anymore.

LCD Miscellany has calculator. It can do almost anything, if you are a bit familiar with C.
