Bring back tides. Add currents

With the new app, the tide information has been removed. I for one found this information very useful for costal routes and exploring. To make this function even better, maybe add a tidal current overlay. Something like Navionics program uses. You can see speed and direction of tidal currents. I know there are many tide charts and nautical apps available but using the familiarity off Gaia with Noaa charts just makes things simpler.
