phuuu... good question...
is "problematic" i think, in the sense that its not helping me. I´ll just talk about mine, im not sure many people actually use it.
Im using it for the first time, cos at least for the moment i dont care about efficent routing of multiple depots.
So its only in use to not circle around storage blocks, where it would otherwise take from the provider and put it back at the requester.
The requester should only getting it from waste products of other blocks and that where i use IDs.
Mostly thats crushed stone, Slag and other byproducts like Limestone from Titanium (that one isnt really a problem as the "storage" is more like the secondary provider, with built in production)
I dont know where it would make sense otherwise. I only use LTN in AB(+MC) games, with lots of small trains, its not like vanilla´s few bulk goods
Thats where the huge number of stations come from.
Its more like the bot network that only carries stuff you dont want to belt all over your main base in a normal game. Its alot of little "transactions" instead of shipping millions of vanilla green chips.
As for filter and/or sorting...
i dont know.... I know very little about actual coding (i know how mods work and can read and understand the files abit) so i guess whatever is easier for you.
I dont think Factorio has alot of alphabetic sorting ingame, but there are search functions everywhere. So i think that would be more convenient for users that dont come here and discuss this. Dont have to be that big of a base to be kinda timeconsuming, even with browsing through lets say 200 stations.
But dont worry about it too much. The mod has already helped me within the first 10 minutes and those things from my previous post are quite common i think, seeing how many people struggle with provide/request thresolds (thats where my assumption about IDs comes), so it might already help alot more people as it is right now.
And i can live without it. Was just a suggestion
This is some awesome stuff as it is.
If i had to, i would say filtering, as its still faster than scrolling through a sorted list.
As tedious as i find it, you should always name stations after what they are meant to do, so if i want see how "item XXX" is doing in my stations (how much is on stock, where is it needed(could be alot of different places with AB)) i would simply filter for "item XXX".
I dont think filtering by actualy items is worth your trouble, if its easy enough for station names, i would gladly take that.
