A new feature(?) in Rosa was to move the dialog windows to the centre of the screen but I preferred to have it on the titlebar, I've looked round the settings but can't see any options to change it, is it possible?
From the Linux Mint feature page:
Dialog windows are now attached to their parent window by default. This setting was already present in Cinnamon (in “System Settings”->”Windows”->”Behavior”->”Attach dialog windows to the parent window”), but it was improved in version 2.8; Dialog windows are now attached to the center of their parent window rather than their titlebar, and the shading of the parent window was made a little more obvious than it was before.
gibbs1984 for bringing this up and to others for pointing out how this new default "improvement" could be turned off.
I'm sure it works in some user cases, but the way my screens and workflow are arranged means I often grab the dialog popup either to move it to a place where it gives me running status or just needed to confirm something from its parent window (now greyed out) and the change was uncomfortably disruptive for me.
Offtopic mini rant warning:
Other new and more minor bugbears with Cinnamon 2.8 for me personally
are 1) the Workspace Switcher app has a few wasted pixels on its top side so instead of just flinging the pointer there against the edge and have it work one now needs to carefully pull back a few pixels, and 2) [FIXED] the new panel icon popup representations are so large and never fade out that they can end up blocking useful content. I'm sure anti-Pavlovian muscle memory will eventually kick in to stop me from resting the pointer up top where my panel is but I'd rather just turn this particular improvement off too.
Of course Mint is still bliss compared to where Gnome and Canonical went with their take-it-or-leave interface dictates.
