I'm suprised, as nothing was changed around saved trips or collections. Same UX as always there.
I'm a heavy user; I use it to plan 3-week-long trips and another month-long trip every year. It has improved, and they do a ton of user interviews to improve it. So far I've been happy.
I'm not happy they fired the old team, but I put that on the sellers and I don't know what was going on there or the company's finances.
