Hmm, the web page that lists all the matrices is around 17MB. I could make
a stripped-down static html file, but that seems like a lot of
(unnecessary) work. It might be better to dynamically alter html and remove
the download buttons of each format, replacing them with a single "download
and run" button. I'll try and see if it can be done that way.
If you can decompress .tar and .gz, what's the problem with first
decompressing the .gz portion and then the .tar? ;-)
Ah. Well. Damn. My bad. I guess I was seeing it as a single file extension,
rather than a combination of two...
Yes, something in the user folder. You can't assume to have write access
to the installation folder.
Sure.
Is this tab needed? Can't this be integrated into the
Matrix-Market-browser with a "download and run" button?
Sure I could check if a selected matrix has already been downloaded, but
one would have to first find it in the matrix market and then hit the
"download and run" button. I was just thinking it might be easier to just
browse through local matrices and use one of those, instead of searching
for it in the matrix market. I dunno, just brainstorming.
