Would it be feasible to add a config option to set custom stats/ranks?

Such that you could use either something like 'Rank 3' or '★★★' or something similar rather than 3/10 or whatever level it happens to be set to

I don't understand what you mean.

okay currently corp stats are displayed as a # out of 10

What I am asking is if it would be possible to set a custom display option for that so that it shows up as something like
Rank 3 for 3/10 or using a single text element repeatedly as such ★★★ for the same 3/10 crop

Basically it would be a purely cosmetic option

Oh, you mean in the tooltips and Waila?

Yah!

Added this client only config setting:

#This defines how to display the stats of plants. Possible settings are 'NUMBER': just display a simple number (ex: "6"), 'FRACTION': number/maximum (ex: "6/10"), 'CHARACTER-'char'': number of characters equal to the stats (ex: CHARACTER-• will give "••••••") and 'KEYWORD-'type'-'keyword'': keyword followed by the type and then the stat, type is NUMBER, FRACTION or CHARACTER (ex: KEYWORD-FRACTION-Rank will give "Rank: 6/10") . Invalid entries will default to NUMBER [default: NUMBER]
S:"Stat Display"=FRACTION

For instance "CHARACTER-•" resulted in:

and "KEYWORD-CHARACTER-•-Rank" in:

Also added a way to define different stat display methods using the API

And yes it works fully recursively, although I have no idea why you what want something like

KEYWORD-KEYWORD-CHARACTER-X-Rank-Because I can

thank you so much!
