Normally not an issue, but with how many games are being added to the big charity bundle, would it be possible when there are updates to a bundle to view specifically what those updates are or sort the game list by most recently added to the bundle?  I'm all for going through all 50 pages to think over every title, that's the kind of gal I am, but its an impossible task when new titles are randomly mixed into the bunch 2 hours later.  It would also make it easier in even smaller bundles to see when something new was added, even if that's just one title.  Maybe consider in the meantime a news feed specifically for this mega bundle?  It'd be very nice just to have a list of whats new as its getting added.  Maybe consider something along the lines of an RSS feed?

yeah this would be a great idea! As someone who has his fingers crossed  his project will get accepted it would be nice to be able to use that to see if I made it.

that or even a "this item is in your library already" label on the bundle download page. like i'd legit don't mind going through each page to check for new items if there was a way to differentiate at a glance and without having to open a tab for each

I put together a more comprehensive spreadsheet you can use to search/sort/filter at https://docs.google.com/spreadsheets/d/1cbOqO6rq0YYWPKmci8Pgv4YGWcl4NQUX9EAj221Ze30/edit#gid=782418878.  You can just use the data filter for batch 1/2/3/4.

While I do appreciate the spreadsheet, it says very little about what each game is.  There are just too many to check every single entry, which means for many titles I don't recognize all I get is the title image and the mini description on the main list.  I am thankful you have made this, don't get me wrong, but its not particularly useful for someone who wants to more casually look over the list and see what catches their eye.
