Congratulations, good purchase.
I avoided the Festool jigsaw until the Carvex, I didn't see what the Trion offered over other jigsaws. I was initially unsure of buying it as my Dewalt was perfectly adequate however the Dewalt is now retired as a metal-only saw. I was also a bit apprehensive about the barrel grip as all my previous saws were bow handle and on first using it I felt it was a little odd, now I didn't even think about it - it just feels right and the strobe thing is something I couldn't be with out now.
If you already have the accessory kit, you will have the guide rail adaptor. Get yourself a rail and a clamp set for it, you will be amazed how clean a cut you can get with a jigsaw with this setup.
Also the rail will be an easy argument for you to then get the tracksaw, routers, etc, etc, etc......
