Here are a few remarks:
Production is either province or region-based.
When you want to go through your realm to check where you may want to build something, there's currently no easy way to know where there's an idle area.
The best tools we have are notifications, but they are region-level and you may want province-level info, and the ledger, but you need to first sort by province, and check the whole list from top to bottom to see if there's an idle province. One by one. You can also click on a province, click next province and check all the provinces, but then you have to check province-less regions, which is best handled by the ledger method mentioned above.
There's clearly a lack of "Next idle production center" button. That would replace notifications, that would kick in when a new pop opens a slot (and thus remove the need of a notification from new pops too).
By the way, there's also a lack of "Province can be formed" popup, particularly considering the "form province" and "cancel form province" buttons are exactly the same and you need to read the tooltip to remember if you already clicked once.
As for the production interface itself:
When you're dealing with a region, it's functional, although I would like to be able to specify some build queues so the province will automatically build this or that, in this order, if the building becomes available at the end of the previous production.
When you're dealing with a province, it's horrible. You click one region, open the list of buildings, go back to the province, select the next region and have to open the panel AGAIN. If you want to go back to a previous region, you do it again and again...
It would be nice at province level to show, in addition to the 'X slots available', the list of icons corresponding to the buildings that may be built there. To the right you could show the possible buildings (maybe even the shuffle button) so they can all be clicked from here. You could still click on the region to get there, adjust, see the effects, etc, but it might help a bit?
Or at least don't close the buildings tab when going from one region to the next, somehow?

Or just make that clicking in that column, it opens the production window on the corresponding region?
It would allow to see exactly when buildings are going to be finished without having to go back and forth. If you have several buildings that might be done in one turn, the current UI is a headache. Build one, check time, go back to province view, select new region, open production, choose, go back to province, compare. And if you want to change, again 3 more clicks with mouse move instead of the expected 1 click.
In addition, there is no way to do any queueing at province level.
Say I want to produce a blacksmith in province A and then a cult site in province B. If I want to do it optimally, I have to check all the possibilities, decide to do A, wait for 2 turns for it to be finished, and then order the cult site in B, which means I have to check every region again and what I want to build, etc.
I would like to be able to say I want both built now, but build the smithy first, so I get blacksmith on turn 2 and cult site on 3 instead of both on turn 3 as is the case right now. So an ordered list of which provinces should build what in what order.
