When using user-written commands, ancillary files are saved in the current folder.
[...] It would be better if the ancillary were saved in the personal folder.

Are you asking for changing the default? You can already change the location where ancillary files are stored with

net set other PERSONAL

which could be part of your profile.do.

Also, wouldn't PLUS be more in line with the idea that ancillary files are additions provided by others?

I have been asking for this since at least Stata 16, but I would really appreciate a -sort- that achowledges sorting in descending order. I am aware of -gsort-, but this fails to set a sorting flag in the dataset for any variables sorted in reverse order.In my opinion, there shouldn't be two separate commands -sort- and -gsort-, there should be a single -sort- that allows sorting in ascending and descending order, and would be compatible with the -by- prefix on those byvars.

I support Leonardo Guizzetti's request in #363. SORT CASES in SPSS works that way, for example.

-egen, concat()- with the -decde- option could be modified to include a -notrim- option to prevent the use of -trim()- or similar behaviour. This saves a step of having to then substitute a character when spaces are desired and then having to replace then again.

I would like to request four new built-in functions in both Stata and Mata, ustrregextf, ustrregexta, regextransform, and regextransformall. All of them should apply a Stata/Mata string function on a pattern in s1. The functions will take three compulsory arguments: s1, re, and t.
The functions were already written by me in Mata, here's the code (I passed "t" as a string scalar, e.g. t="ustrupper", but maybe a different solution can be found):

The ability to enter in custom subgroup means in Stata's meta forestplot suite just like the customoverall option allows.

[ericmelse]

By that I mean allow Stata to read pixel data from images in PNG, JPEG, TIFF etc.

Gradient colors would be interesting as it allows for transition of state. Imagine a sankey plot with gradient tones.

Even better, we very much could use the ability to use gradient colors (tones) in between color points / positions on objects created by Stata's graphics engine.
And indeed, that would be most useful for alluvial and Sankey plots but there are other applications.
For example, instead of using twoway contour plot with area shading, we could use the x y data points [0,0] and [1,1] (or any other value), set their color respectively to white & gold and create this effect to color the plot area (using the suggested option to set gradient colors):
