Not sure I understand what you mean, can you clarify? Perhaps a link or a couple of screenshots?
The my posts page would show posts in full on the posts page, but it also let you open the thread to that post and read the edges around it. That was great, except you couldn't filter by reaction here.
On the Reactions page, you could filter reactions, but the page of results wouldnt show the full message, only a truncated version. Further annoyingly, you couldn't click a post and go to it from the reactions page, it just kicked you to the 1st page of the thread.
.... I was, admittedly, repeating a userability issue I requested on GAF a lot. I assumed it was perhaps a limitation of the board software but couldn't hurt to ask here as well.... anyway, when going to take screenshots, I discovered IconEra's reactions page does include both a link to post and link to thread, across desktop and mobile.
I guess this feature request can be ignored. lol
For comparison, GAF's reactions page does not include a link on the 'your post' text, as shown here, making the page ineffective as described above:
