DECIMATE MODIFIER: showing reduced info in %

Hm... you know.. I feel that probably no, because there are all different names of this sliders, for each approach (collapse/un-subdivide/planar). So like it's non general thing as I see.

It should be useful for example in case when you need to compare how much it was reducde mesh (between approaches or at general, without no need so precise accuracy) how much it was compressed (and you no need to turn it on and off modificator or going to the statistic tab and comparising two different counts of dots/faces) especially if mesh is heavy (or PC is low) turning on/off midificator is going slow(when it updating mesh).

So.. I've literally described this situation from own experience as blender beginner :D

And yes, you right that for beginners it's not important difference in 2%. But when they can easy see that visually between 10 and 20% not too much difference (when theylooking at viewport at same time and choosing method and tweaking sliders).. it's much more easier to choose those one that not so heavy for scene.

version: 3.0.0 Alpha, branch: master, commit date: 2021-09-18 19:45, hash: rBbdbc7e12a02e — I don't know how it possible, but I have checked it with factory settnigs (from inside/ as from manual settings folders too, by deleting it) And in v2.8 I watch it same. I even downloaded just right now fresh 3.0-alpha and there are no difference.

The point to be able fast and easy understood between this three approaches their reducing possibilities and without no need to going to statistics and turning on/off modificator

Just changed Factor display type .

And i still dont know what the problem and why people upvote this.

"0.3" is literally the same exact thing as "30%", everyone should know that it was in primary school.

I think the goal here is to get a more understandable readout of the end result (the number of faces as a proportion of the original mesh), not a change to the way that the reduction ratio that you're inputting is displayed. Three reasons why this could be useful:

1. Collapse ratio doesn't always correspond to a 1:1 reduction of faces on more complex geometries.
2. Unsubdivide and planar modes in decimate have different controls (iterations and angle, respectively) which don't clearly correspond to a percentage reduction by control.
3. Even for the Collapse mode, having a comparison of the input ratio and percent reduction in vertices could indicate that there was a problem that Decimate can't fix (for example, a large number of duplicated vertices that aren't joined to the end mesh).

To @zuorion - Oh, thanks. I even didn't know about ability to change this settings. Should try it now. But I still think that it don't give ability to compare between methods/approaches of Decimate modif. That was described as second reson by @desksonmars. Probably that's why they still upvote. And probably begginers as I am don't know about this trick inside settings too. And by default it shows as Factor. Probably this too add some votes.

That feature motivation should be in original proposal and not just "add percentages" with screenshot of percentages.
