XnViewMP 1.4.5 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

General
'Insert' ⯈ menu (eg in Settings>View>Info tab) has a lot of ungrouped items

Suggestion A

(blue - modified items)

• group 'Insert' ⯈ menu
  there is nothing bad 3 level menus when used for grouping
  - menu will look cleaner
  - it allows to navigate easier as menu will not be polluted with different UOMs
  
  next step - group EXIF - Image menu

Suggestion B

there are too many ways to label 'Insert' button

• unify progressive disclosure buttons
  to Unicode symbol:
  (need to check which one looks better)
  ▸ (U+25B8) Black Right-Pointing Small Triangle
  ⯈(U+2BC8) Black Medium Right-Pointing Triangle Centred
  › (U+203A) Single Right-Pointing Angle Quotation Mark
  » (U+00BB) Right-Pointing Double Angle Quotation Mark
  
  in:
  - Slideshow (settings tab)
  - Contact sheet (settings tab)
  - maybe somewhere else

I've tried to not have 3 levels, for me 3 levels are not clear but perhaps i'm wrong

i would not use 3 level for something like site navigation dropdowns or often-use-items,
but here its fine as it provides more benefit (cleaner menu) than harm
