I think it would be good to include the script to fix permissions of eink framebuffer to allow regular applications to write to e-ink without root permission as descibed in this post
Also if you ever get to building Edge Sr Update, it would be good to include fix for crashing built-in browser described here
Deleting the telephony related applications would be useful as it was reported here
to save battery life.
Regarding Javese applications - since they are not available through the market installing them later will require digging through forums/backups. So I would vote for including them in update file, but in case of e-ink viewers only the versions that do not require root, if Javese could find time to provide such versions. Otherwise in case of fbreader which is open-sourced
I could provide modified version.
And while you are at it, maybe you could in parallel create a regular (non-golden) update file for allmine with all the goodies that will be suggested here and accepted in your golden. Would be nice to have equal updated functionality.
Thanks for you effort!
