When you are in the wilderness killing all kind of folks, there comes the time when there is no more room in your bags. You now have to consider which of the trash you would like to drop. If you have the NISP addon you at least see what each item is worth, but it is still a mess in those bags and finding the trash with the lowest sales price is like a mini game that you don't want to play.

Here comes JunkDelete!
Whenever space is getting low (1 slot left) it evaluates the value of your belongings and chooses the item/stack with the lowest value to drop next - and tells you so. When the last slot gets filled up, it instantly drops the item with the lowest value - that could as well be the item you just picked up.

In default mode JDEL only drops grey items upto a max price of 10 silver.

These are the options:

/jdel option [value]
l[ist] -- list all droppable items (regarding the current setting) ascending to sales price. Top one will be deleted next.
s[ettings] -- list the current settings.
w[arning] -- toggle warning when nothing can be deleted.
n[ext] -- toggle announcing the next trash item.
m[axprice] value -- max price for deleting an item/stack. You can enter a pure number, which is seen as copper, or any combination of g(old), s(ilver) and c(opper). Example: 1g 10s 5c
slots 'value' -- set num slots to keep free to 'value' (1-10).
apo -- toggles deleting of apoth items.
apo 'value' -- only delete apoth items upto level 'value' (1-200).
cult -- toggles deleting of cultivating items.
cult 'value' -- only delete cultivating items upto level 'value' (1-200).
salv -- toggles deleting of salvaging items.
salv 'value' -- only delete salvaging items upto level 'value' (1-200).
tal -- toggles deleting of talisman items.
tal 'value' -- only delete talisman items upto level 'value' (1-200).

So if you don't care about talisman making items just enter "/jdel tal" and all those low priced items will be dropped to make room for better ones (regardless of color/rarity).

As long as you don't fully trust or just want to know what will be dropped next you can leave "announcing the next item" to ON, otherwise toggle it with "/jdel n". And if you do not want to see the warning that there is nothing left to drop with your current settings just type "/jdel w".

Just try it, your gathering experience will completely change.
You can set the client to "take all loot" all the time, not caring what trash stacks in your bags.
