Any additional tool can be useful and this also.
But I much prefer to group the Regions so I will have a few routines within each Region and then I will have no need to order the routines by name.
Even routines you listed are few; anyway, I will divide them in:
#Region + Files functions
Sub is_directory
Sub is_file
Sub makeShortPath
#End Region
#Region + Pseudo properties
Sub SetBackcolorToolbar
Sub SetBackColorStatusbar
#End Region
...
For this reason, I would prefer that the window which lists Modules and Routines display also Regions (this would be even better if the Regions contained Routines, but I suppose that there is some technical problem to create a tree view in that window
, given that the Routines are not displayed within the selected Module but listed below).
P.S. you could also use two big "external" Regions:
#Region + Public methods
...
#End Region
#Region + Private methods
...
#End Region
