Thank you Galv, I played with your plugin a bit, and I have these suggestions, of course you will do it how you want, what I will say now is just an example that you decide if follow it or do them as a new complement, but for understand better what I'm suggesting (also is how I see it in my head) I will tell the examples as an improvement of the current plugin:
After did several tests of your plugin, and keeping in mind some battle systems that will use even more than 6 actors in the battle, your plugin is really brilliant for display the actor busts even with a total of maybe 18 active members. So here are my suggestions for make this plugin really, really amazing (huh, maybe this will need a rewrite of the code :x ):
Considering that is very possible to fit up to four or even five rows of actors if the game resolution is 1920x1080 or bigger, you can do that the first row is displayed in a certain size, and the next rows are displayed in another size, for example...
On Bust Height, we can use comas to define the height of each row, for example (pure example, got tired of test several sizes x_x): 1000,800|800,440,260|800,440,260
1000,800 is used on the first row, that means that when there is only one row, it will be displayed completely, when there is more than one row, its maximum min. size is 800 and the next rows will be displayed below the first row. 800,440,260 defines the sizes of the second row, being 260 the max minimum size when there are three rows being displayed (which can be a total of 12 members, being 4 members displayed in each row), and | separates the min and max size for each row.
We do the same for the rest of parameters (Name, Class, etc), but instead of pixels, is an amount of lines, so if we don't want to display certain elements like exp bars on the other rows, we write 0 or -1 for hide that element.
Also, another parameter controls which rows will be centered, the parameter can be called for example "Row Alignment", if we write "2,1,3", that means that the first row will be centered, the second row will be aligned to left, and the third row will be aligned to right.
Also, two more parameters, controlled as the ones of above with , and |, that let us control the line height and font size for the elements of each row, so we can adapt much better the display of the rows. For the font size, I guess that will require to be individual for each element, for example Name Size, Class Size, etc, because there are some people that might like display the Name and Level in full size but the HP, MP, SP and EXP in half size for the next rows hiding also the state icons for give more space (assuming that you didn't provided an option for resize also state icons

: ).
Lastly, will be good if there is a built-in (or an extra complement so if we use another plugin that changes the display of the menu, we can disable this) parameter to define the size of the command and gold window,
however, if you link to Yanfly's Main Menu Manager's article for download his plugin, you won't need to add this feature, personally I think that there is no need to do that, maybe even Yanfly let you to add his plugin inside your zip for the people that wants change the size of the command (and add many more features for control the display of the menu).
Examples with Paint:
Huh, seems that I ended suggesting too much things

.....................................
......................sorry
PS: Maybe will be good divide the Busts Offset of now to Busts Offset X and Busts Offset Y, so we can control the offsets of each row more easily.
And again, what I said was just examples, do it how you want! Upgrade the current plugin or do new complements!
PS2: If you read "arrow" somewhere, I meant "row", I don't know why I wrote "arrow" several times.... lol
