Well, one way of working around the locking latch position of the T-loc system would be to move the drawers to open from the ends of the systainer instead of the sides. Then the T-loc latch & nob can take as much space as they need to and still retain full volume utilization of the systainer (assuming that backward compatibility would be dropped and the old side latch connection point could be removed). This could go two ways in either enabling a lot longer drawers than in possible today or two shorter drawers one from each end.
Heck, if Tanos would like to make a sexy Sortainer NG they would make the long side of the systainer above the T-loc latch an translucent flip-down drawer a bit like the attic lid and have the drawers behind that opening from the sides [tongue]
As far as I can see in the situations one would use a sortainer it would be out in the open, so all sides of the systainer would mostly be accessible.
The main downside that I foresee would be when a sortainer with end drawers is situated on a shelf / systainer rack because then you would need to slide the shelf open to access the side drawers.
I see the option an integrated drawer sortainer with a standard size systainer box compartment and attic lid on top to be the next generation standard tool systainer with better accessory storage options vs. the current multi-level inserts and stuff just thrown into the systainer on top of the tools - not as a replacement for a full-blown sortainer for only keeping organization of loose things.
So I would like to see both versions available - sortainers with T-loc latches for organization of small stuff and Systainers with integrated row of sortainer drawers at the bottom to have tool specific utilities storage separate from the tool storage compartment.
Just comparing to the CXS set I have I would rather have the attic lid which is great + a standard T-loc SYS1 size compartment under it with the normal insert for the CXS+battery+chucks+charger only + a single row of three drawes to a side half way through the systainer each with compartment dividers for the standard drills, hook adapters, screws, fasteners, etc. that I currently carry in a separate SYS1 with the screwbox inserts attached to the systainer and have to balance with the CXS systainer in the connected position instead of just pull open a drawer. Currently I have nothing in the second insert layer of the CXS systainer because its just too much of a hassle to pry the top layer out of the systainer with your fingernails and try not to drop your drill from the cart when its out - so its effectively a waste of space.
I guess ideally (if space permits) the tool storage insert would have a dedicated space for every accessory the tool has, but no additional 'general utility spaces' and the generalized space would be provided in the form of an attic lid + drawers under the tool compartment. This way the tools would stay nice and tidy with their chucks, connector bars, DC adapters, etc. and all the random stuff would have a place out of sight in the drawers. Large items line TS-saw blades would probably be counted as standard accessories and should have a spot like they have in the current systainer insert.
My router systainer is so full of stuff that it takes 10min to just pull a table full of router bits, biscuits, DC connectors, templates, extra copy rings, etc. out of the box that I seriously think twice before pulling the tool out. And its a jigsaw puzzle to get back together and close the lid. [embarassed]
