Controller presets should be listed alpahbetically in drop-down menu

[ronso0]

Title says it all.
Furthermore some presets appear to be in alphabetical order. One wouldn't go back to the top looking for 'Txxxx' after sorted presets for 'Rxxxx' and 'Sxxxxx'. This might drive impatient/superficial users away when trying this nice FOSS dj software.

Noticed this when looking for my updated preset for Reloop which showed up near the top.

Can you reproduce this with a fresh profile ?
mixxx --settingsPath /tmp/mixxx-profile

AFAIK mappings from you user preference directory show first (alphabetically sorted), then mappings from the system-wide mixxx folder all appears alphabetically sorted.

This could explain why you see your own mapping first or near the top after having using it once. It always show first the mapping you have already used.

This is what I did, actually. Built r6024 and ran it from build dir with
./mixxx --resourcePath res/ --settingsPath .mixxx/
I removed .mixxx/controllers prior to every test and the changed preset always showed up near top.

Just tried it with 2.1-alpha-pre from the repo and clean/no profile.
Entries are in this order
Kontrol DJblaa
DJTech DJM-01

I have noticed this lately too. It did not used to happen. Not sure what changed in the meantime.

Without using a Controller you can whatch the bug by starting Mixxx with
mixxx --developer

Options->Preferences->Controllers->Expand Tree->Midi Though Port-0

The Combobox with the issue is "Load Preset:"

I found the position where the presets are added in the combo box, this is at src/controllers/dlgprefcontroller.cpp at line 241, where the void DlgPrefController::enumeratePresets() starts, in this function the addition of the presets to the combo box takes place, so here only left task is to sort the presets in the Lexicographical order, which I can do with the function sort of the standard template library

Or any other function I use which have better time complexity than Nlog(N), (may be not present such function yet), yes especially for this length of data please tell
