Feature request: Show both toots and boosts of a person in one tab

[genya0407]

I would like to have a feature that allows me to see a person's toots and boosts in one tab.
(related issue: #1836)

It's common for users, myself included, to boost a toot and subsequently post about it.
For instance, I often boost news-related posts and share my thoughts on them.

Currently, IceCubes's profile tab separates posts and boosts, which can disrupt the continuity of the conversation, as in the example above.

Perhaps we could introduce a "combined" tab in addition to the existing "toots" and "boosts" tab?
