As a GM you need to be delegating some of these duties to your players. Initiative tracking is a prime example.
Print out and laminate Stan's Combat Tracker. I found it on the Stickied resource thread and use it for my group and it works great. However link doesnt appear to be working ATM.
Looks like this is the creators website .
I prefer to keep track of this myself actually. After doing this for 26 years its really no bother. Its more of a convenience thing really which is why i requested it as a long term project. That sheet is nice and tidy, but it takes up table space and i have a lot of other stuff competing for that space.
I use my laptop as my GM screen, and track initiative order on it to save space. There`s also a lot of quick reference stuff on wookiepedia, OggDuse`s tool, various on hand pre prepared one offs (often concerning the players obligations), a main story arc, random name generator when i need one in a hurry and a bunch of other nifty tools. Then there is the main book, a few reference sheets and so on. It adds up. The rest of the table is cluttered with character sheets, a huge laminated galaxy map, a bunch of coffee mugs (which is why the galaxy map is laminated, yes my players are slobs), various food of the healthy and very unhealthy variants, handouts and so on. You get the picture. Having easy access to stuff through OggDude`s tool would be a great convenience.
If you are running a book story you dont need all this stuff, but when you create all of it yourself and often run in sandbox mode i find myself needing access to these tools.
