yes, it is necessary, when you start the game, usually you create your ship or your industry with basic elements.
It would be so easy to click and choose an options to replace an elements with one of its superior version... but no, you have to empty it, remove it and then put the upgrade back in the same place, refill it and reconfigure it... just really laborious for nothing.
in many others games...  right click "upgrade" and it's over (in our case it's obviously in condition of having already created the better version and that one be available in inventory or container).
it should already be in game ^^

hello, I think it would be a very good option if you could upgrade an engine by right-clicking on it like replacing a broken engine.
for example I have a basic engine on my ship, and I want to replace it with an advanced engine.
I put the advanced engine in my linked container and then when I right click on the basic engine, it offers to replace it with my advanced engine which is in my inventory.
without cutting the links to the tanks
that would be really great as an option, wouldn't it?

if i select a specific number of things to build it'd be nice to have a gran total of each element needed in the summary that shows the recipe of the thing being made. it saves me from the simple math of multiplication (which i still avoid by escaping out of the window and selecting 'k' and putting in a sample order to see how much of each thing is needed. it'd be nice if could do it all in the one window. 

Is there a possibility to get market information via lua?
