Description

tmap v4 is progressing well. The plot mode is almost finished, now working on view mode. I'm trying to implement as many There are a few features that would be nice-to-have:

  • text that has a fixed position in the window (for tm_title)
  • text that has a fixed position in the window (tm_credits) #806
  • legend symbols other than squares
  • landscape legends

Are there leaflet extension packages that can do this (@tim-salabim) ? For the current version, I implemented the titles myself in a pretty ugly way, so hope to outsource this for v4.
