@Faeryl Thank you
In depth and detailed explanations (and more)
@Pandagnome Legacy just means in this case, the original design (complexity wise) that has since been simplified due to the nature of upgrading packs and what it's usual purpose would be.
However as
@PartTimeJedi mentioned it
[here] , requesting a cross comparison and we already had the code mostly functional, we just released the old UI with the functionality working similar to how it works on the main one. The thing is that it ended up being niche and we didn't work on the UI since, you will however notice that the new packs that have since been introduced, have been added to both as it works the moment I update the info listing on both.
Also for the "phones" bit, it was just a more widespread use as of this time, it applies to any smaller windows, even on a pc if you shrink it, works the same
