A couple of versions ago, after the update, I realised that the develop sliders had shrunk. I thought it was a GUI design change until I switched to English. It was a surprise to discover that in my language the sliders are a lot smaller. I'd get it if it was because of a long caption that needed more space (as it is in Temperature) but as you can see in the screenshots provided, there's a huge amount of free space that is not needed for the caption. No need to say I haven't touched the panels width.
I was waiting till the next update hoping this was fixed but in this last release it's not done yet.
