[Feature] Option to show sum of size and not maximum size

[TabNoc]

Hey, I really like the application, but I often feel the need to display not the maximum amount of space a directory/file has consumed in a snapshot, but instead the amount of data that was aggregated in the different snapshots for that directory/file.

For example (but not limited to that use case, I have multiple) I have a backup of my personal PC. There I have configured a bunch of exclude rules for the different applications caches, but I have missed some smaller cache directories. Some of these applications write ~30MB of data in each and every backup, which adds up quite a lot, but is barely detectable with the current feature set, as this directory will never get bigger that these ~30MB.
I have thought about implementing this feature myself, but I'm not even that sure, how to tackle that from a technical perspective, as that would probably require to count the data blobs themself to check after the de-duplication? And to do that in a manner, that could be speed up using a cache would also help immensely, as the rest of the application is doing.

Hello.

I think this would actually be a worthwhile feature. Maybe allowing to toggle between these two modes or something like that.

As for the implementation strategy.
I think for something reasonable we would have to fetch the blobs as well and store their size in the cache, along with some relationship between paths and blobs (i.e. this path references these blobs).

Presumably for each directory you would recursively add up the size of all (unique) blobs to get the total size.

I currently don't have time to work on this but I would be quite happy to provide guidance and discuss anything if you want to work on it.
