@salvi.yordanov you have all of those Systainers that fit in your Bott racks (looks great by the way) but only 2 of them are actually Festool, which kind of proves the point.
The other "improvements", whether you consider them to be an improvement or not, don't compare to the screw-up of changing the vertical heights. As [member=75933]luvmytoolz[/member] has said, probably as many times as I have, that just trades one "system" for another. Sysports and homemade cabinets in the same constraints were designed around those heights. Granted, not everyone who owns Festool equipment has Sysports or even uses them "fully" (to the designed capacity), but there are a lot of us who have built an entire wall of them.
I can't even imagine what it has done to FUSA's massive wall full of them? They have so many Sysports stacked that they are impractical to use, but it's surely an impressive display. hey can afford to waste the space and keep things in a more grouped together manner, rather than making di with "that's how it has to be, because it "fits" that way.
Mine are arranged as best as I can, by frequency of use, area of use, and somewhat by the size of the tool itself. I would like to have one more unit, but space is becoming a thing. If I add to the end of the run, I would have to move the cutting table. I don't really want to do that....too far off topic, sorry.
