Well I can't speak for the others as they are just working on their respective utilites whenever they feel like it, but lazarus itself and it's wrappers are developed in sporatic bursts.
When my brain is working I can make a lot of progress in a day or so, but when it's not it can take several days to get motivated enough to even work on them.
I'm not working on ANY of the helper utilties as everyone else is doing a great job without me, I just have to give them any needed info about configuration options.
Right now I'm working with >p< to make 3d arcade and lazarus inter-compatible. This is extremely long term, but the idea is to make it to where you can setup one and it will automatically setup the other for you.
Even further down the road we want to make it to where you can run both on the same cab..... your cab will boot up and you will be prompted with a menu of which to launch. You can go in, play a few games, and then exit to the main menu. If you go into the other fe, it will automatically be in the same position on the list that the previous fe was at, with the same color scheme/skin loaded, ect. This is all planning right now, but it's kind of fun to try and we will have a great setup if we can pull it off.
