Why are moodlets not sorted by time remaining?

This is something I keep an eye on, not only in sims but in other games too for my inner peace. In another game I got a mod to sort moodlets (they are called buffs there) by time remaining because like in the sims they keep jumping around by default. With my settings the oldest or passive auras are first and then the timer gets smaller and smaller. This is so satisfying to look at. Also it makes it possible to read some of them.

Now in sims its a whole different feature. The sorting seems arbitrary, The list auto collapses after one second the more moodlets we accumulate. Which has been one of my biggest nemesis' in the game for a very long time especially when I found out thats intentional.
Most of the time I could only read what they do by pausing the game. And the blinking is super annoying the more moodlets are about to expire.

Then there are moodlets with an extra white frame around them. Apparently those are special moodlets. Somehow. But most of them are no different than the moodlets without it.

Now with a mod I have the list always expanded. Its called "Keep Buff/Moodlet Panel Always Open". Sometimes a sim has so many moodlets that they hit the pause button. Doesnt really bother me because I can still reach them to read what each moodlet is for.

But it blows my mind that this pretty vital feature doesnt get improved.
