A lot of things are possible and would help this:

- change your system to auto-logon your account and start the
applications for you. This is possible without any coding.

- do per-user readahead, so that when a user logs in readahead-collect
runs again but with a different pack, stored in the users home folder.
Most of this should be possible with little work, but you'd have to
write some xdg autostart files and possibly patch the readahead

- extend the collector to run much longer

- manually create a pack and disable the collector

one of the problems is that it's hard to create something that
generally works well for all situations, and autologon+lock desktop
benefits from simplicity since readahead catches almost all of it.
