Add Option to filter out unoptainable items

I literally just created this account to ask about this.

Would it be possible to filter for everything that is actually optainable in some way? For example, I haven't played Overwatch in Season 1 and 2, so there's no way for me to get these sprays and Player Icons. It would be nice if the Tracker does not count them towards my total number of unobtained items.

This is a good point, never really thought about the comp items as being unobtainable. I'll add it to the backlog though this shouldn't be too hard to but in general I wouldn't really worry about the All Class items. They're kind of hard to track anyway.
