Before the upgrade I was using 14.04 and I was happy with alt+tab and alt+` behavior for switching between apps and between windows of an app respectively. Both showed me the items in last recently used order, in particular single alt+tab always switched me to the previous one.
Now, in 18.04, I can't help understanding what order it offers to me. It looks like it's not last-recently-used any more. Sometimes alt+tab switches me to the window already active. Sometimes to get to the previously active window I have to do alt+tab+tab+tab+`. Is there any way to restore the intuitive behavior?
Also, an annoying thing is, if I switch to one window of an application, the whole application is brought up. Any way to disable this?
