[SOLVED] Make apps open in the center of the screen

[Grave Digger]

i know from when i was running kde neon in plasma i could change a settling and have apps i open open in the center of the screen instead of snapping to the top left edge. i've done a google search and everything keeps pointing me so a section of system settings that seems not to exist. i don't believe it was removed, but rather i'm just not finding it. help finding it would be great. thanks

hey thanks again like i said that worked perfectly, but still seems to be one suborn program. i have 4 desktops. 1 is applications, 2 is browsers / email, 3 is dolphin, and 4 is a spare just in case. now when i'm on the dolphin desktop and i click app it opens in the middle of the screen of the desktop it's assigned, the exception is smplayer. sm remembers which desktop to open on, it's custom size, but still snaps to the upper left corner. i honestly don't get it cause as with the other apps it should automatically snap to the center of the screen. any idea what might be causing it to misbehave? thanks

smplayer has explicit settings for this that may work over custom window rules, and may possibly be overriding them, or it simply does not support following some custom kwin rules.
I have installed the Bionic version as I am on KDE Neon, and also cannot get the rules to work, but Smplayer's own configuration has a setting for this which does work for me:

thanks that looks to have done the trick.
