Depressurizer VS Rarismas-Server-Manager

Another thing you can do is use a Steam tag management system like Depressurizer to automatically tag games with their approximate HLTB time (eg. 1-5 hours could be a category, 6-10 hours could be another category), then on Steam Deck you can use the Tab Master plugin for Decky to show each HLTB categories as a separate tab. There are probably other ways to display the categories as well.

Lucky for you https://github.com/Depressurizer/Depressurizer was -Dead- for many years past after New Steam Library but resurrected last year and it's the perfect tool for organizing your games.

Strange? I was going to mention, in the past, there was this great tool called Depressurizer that can help you but after New Library introduced few years ago so that project gone dead, unable to adapt to the new system. But you must be lucky that https://github.com/Depressurizer/Depressurizer has a "New" release that may include HLTB info like they did in the past.

I did this once and Steam deleted my meticulously sorted system so I figured it was never worth the effort again. Depressurizer is a tool to do it for you based on some basic filtering.

It stopped working long time ago & that's why that project is no longer working. Also this isn't a bug as Valve never intended anyone to tamper with sharedconfig. Even if you may still see that file in Steam installation, it's kept for backwards compatibility & backup instead of new library is kept in an enigmatic coding in some another file.

You can use something like https://github.com/Depressurizer/Depressurizer to Categorize the games for you.

Use https://github.com/Depressurizer/Depressurizer. This will allow u to categorize the games to ur liking. plus u can use favorites to categorize the games that ur currently playing while collapsing all the other categories. this may help with the clutter

Not 100% sure if it has data export functionality, but if it does then Depressurizer might be worth checking out.
