Hello @Earl_Quijano and welcome to the forum!
I just checked the 5.2.1 for a possibility to resize the recent images display area, that is unknown to me, and after searching for a few minutes I have to say I was unable to discover a possibility to resize that area. Can you please tell us how that should have been possible, so what had to be done to resize that area?
Because before we can confirm it ever existed, we need to know how it worked so we can check the 5.2.5.
Or do you mean the possibility to manipulate the “free space” on the side of that area, because there is a way to do that as you can read in this topic:

Add/Edit: @AhabGreybeard, @raghukamath, @Sooz, in principle this post and the one above belong into an own topic in the Basics & Interface category.
Do you think the same? And if so, could you please cut out these two posts to create a new topic in Basics & Interface for them, so this can be further discussed in its own dedicated topic?
