As per request by many non-users, I will compile the next version for 1.4 target. That should help it to work on most of the platforms. The next version will be coming up shortly, with many added components and a nice example theme file.
One major improvement would be the ability to install themes to 770 user space. At the moment installing a new theme requires root access, but if the themes are installable to user space, then ThemeMaker could save themes as installable debs. I am still waiting for confirmation on whether this is possible for the current version or will we have to wait for the 2006 OS for this to be possible. In any case, I will probably pursue making the install files as .tar.gz files for the future releases. I have found a nice gpl java based tar library (which includes support for gz), so packaging it should't bee too hard.
And for any linux users out there, no, I can't just use linux tar command, as I haven't found a good tar exe for windows. If anyone has an idea on a good command line tool for making tar iles on linux (which is gpl), then that would be much appreciated.
Oh, one more thing that I've left out is the icons. It seems that most (or atleast some) of the icons have a white background. This is of course depressing for anyone willing to make a theme with other main color than white. I hope I can package replacement icons that have transparent background, but that won't happen for the next release yet.
