First, welcome! Second, the
pkg_* system is deprecated and you should use
pkgng now.
I had used Linux for many years before I started using FreeBSD, and felt the same lack at first. You can go to
Freshports and search there, but it's probably easier to use Google than their limited engine, although if you look further down on the right hand side of the Freshports page you'll see "Categories" which is handy.
The GUI based program management systems you will find in Linux are quite handy for discovering things, but I think there is a good reason why FreeBSD does not install software in that way. Yes, you can use
pkg, but this OS is generally intended for servers and people in that world will often want to use ports instead. You should probably go to
/usr/ports and have a look around there since that is a local place to see what's all available. Also, read the handbook - it's cool.
