I was able to import all my existing NYC geo-points into Felt and quickly chart some itineraries from different sources. Way, way faster than Google Map.
Let's see how fast it will render once I'm on the ground in the city with mobile interent.
One major difference with Google Map is the lack of custom layers, but so far it hasn't been a problem.
This is my NYC 2022 trip map :) https://felt.com/map/New-York-2022-u7J1aE2ZSLOmdwCP4WGCOA
