I have been wrestling with a big sessionstore.js since I discovered tab-groups, I have been trying to find remedies to performance and recovery and have not found anything. A few times per year I go looking for inspiration and it seems there is little information about the status of these upgrades. Is there some way to do steps 1 to 6 manually (perhaps a plug-in)? At many times at the end of a day I like to think that I am at a place that I could do a clean-up. Mostly my tabs are used for side projects and tool groups so they do not need historical context, I would just like the URL stored. I would very much like to have the start-up faster, tag group switching faster and less clutter in the sessionstore if it were to crash and need recovery. Leaving more historical data by default could be done in pinned tabs perhaps (though not needed by me) and this would be a way to preserve state in those tabs that are important to maintain forms data etc. >From a privacy point of view this is going to become increasingly important. >When the session store breaks it often leaves old copies that remain unless >manually removed. It would be nice if they contained a bit less old data.
