1. Why I can't save all my personal settings in one $@#$^% file in 2017 year??? 2. Why you removed vector snap checkbox long time ago and didn't return it for these days? Who the @$%@# ask you for it???? 3. Why I can't drag my artboard if it fit in my screen???
C:\Users\Username\AppData\Roaming\Adobe\Adobe Photoshop CC 2017\Adobe Photoshop CC 2017 Settings\
There you can find the Workspaces folder. Copy to CC 2018. Fire up cc2018 and use the newly added profile.
Other settings are located at C:\Program Files\Adobe\Adobe Photoshop CC 2017\Presets
Hope that helps.
PS: In the Settings folder are a lot more settings you might want to copy to the new CC Version, like custom gadients. And yes, this sucks, but make a shortcut somewhere to the file location and regularly backup the folders.
