SER upgrades over-writes file "content_search"
You have several popups asking to overwrite or NOT existing files when installing an upgrade
the one overwrite protection currently missing in your overwrite protection list for upgrades is the "content_search" which might be edited for local picture search.
may be you can add a popup question to save personalized "content_search" as well ?
may be instead of overwriting such files - ADD the new version with a NEW file extension
the latter is a common method to protect personalized config files in the Linux-world.
this method allows the user to view newest files and see if anything new and useful might be added to his personalized configuration.
I noticed you do lots of improvements / upgrades and sometimes the download is quiet slow, even aborted = time out sometimes.
did you ever consider offering your upgrades via BITTORRENT files ??
it saves YOUR server resources and is lightening fast = much faster than an average direct server download. (for example opensuse.org offers the download of the entire OS (4+ GB) and is done even HERE in KH in less than 1 hr
