image shows what's suggested.
layout and what info is on that line can be discussed of course.

some suggestions are:

• number of episodes downloaded
• total size of episodes downloaded
• average size of episodes? to identify if any episode differs very much from average
• for example count of x264 vs x265 and other codecs counters (needs that info in the db of course)
  see [ FEATURE ] media metadata #577

important note here. if there is an episode S0XE03E04 for example. do not count the size twice for the total season size.

here is a crude example of what i mean. i do believe it could be even better to move the sizes in relevance to the Size column already used for episodes etc, but still it's an example.
