I notice it lists posts I have commented on under the heading 'pending author rewards'. This confused me for a minute, as at first I thought the app was crediting me with authoring the posts. Maybe I'm just particularly easily confused, but maybe you could specify author rewards for posts and for comments, just to prevent anyone else from suffering that momentary confusion, and to enable comparison of rewards from these activities.

Technically speaking rewards for posts and comments are both author rewards.

Also, I always assign some of my author rewards on my posts to beneficiaries, and it would be nice if those amounts were tracked, as well as tips I provide or receive, so I could quantify the impact my use of those tools is having on my account on an ongoing basis. In the column to the left at the top of the report several items are quantified, such as delegations in or out, and etc. Beneficiary rewards and tips I provide also substantially affect my account, which would be nice to see there as well.

I'll look into it. But I can't really promise it. Depending on how hard it would be on the public RPCs it might not make the cut.

I haven't spammed the userbase with .01 Hive to request some attention, but sometimes folks do that and they might benefit from quantifying what they spend that way.

I think this would be out of scope, there are better tools to gather such information. And this project is mostly about rewards of your account.
