ebox = yes, guarana = no, els_box = never saw.
why ebox and not guarana? Because the current code will be similar to
ebox, it's a bunch of items laid out in some way, that is still not
available in guarana (we call it "sequence_box" here, it's being
finished and will be pushed later today -- actually I want to use code
in Guarana sequence_box as base for what we plan to integrate in
evas/edje).
what is guarana base_list, single_selection_list, ...?
These are optimized MVC lists. They're limited in some ways, but
they're very fast, having the complexity bounded to number of visible
items only (O(n_visible)), so if you have a huge list it will not slow
down your code in any way.
But it's limited (on purpose, some things may change, some may
not), one thing is that every row must be the same height, so
calculations take place as a simple math. Also, row renderers should
be the same, since these will be cycled for all items (we just
create/destroy renderers when viewport is resized). However this makes
a perfect base for large lists like your whole music collection ;-)
