Select Area Feature for Epub files
This feature "Select Area" is great one because we can add some equations or figures side by side to highlights with other annotations. Please add this importune feature "Select Area" to epub as well.
We could consider having a modified version of the area-annotation tool that let you select by page element for EPUBs and snapshots. That could let you select specific images, for example. You just wouldn't be able to use it in the same way, where you could select an arbitrary rectangle on the page, and thumbnails wouldn't necessarily be consistent across devices.
