Yes, it's very easy and intuitive from a PC. Getting your hotlist sorted makes everything a lot clearer. (Apart from the default) I have a "seen list" (I forget at times!), a "TS list" and a "Top 5 Tarts" list (for escorts I'd like to see again; it only has 4 so far!).
The other thing that is useful is to have a rough idea of your hotlist maximum. Then, when you get to around that number, have a cull of those who you are realistically never going to see. Otherwise, the whole thing can become unmanageable.
