• Improve color palette options Color palettes: native support for the pals package? #566
• Improve inset legend placement
• Add view mode plotting functions
• Add tm_basemap (probably using maptiles)

• Migrate tm_symbols symbol options (icons, grobs, pngs, etc) from tmap3
• Add tm_grid and tm_graticules
• Migrate map elements (tm_compass, tm_scale_bar, and tm_credits)
• Think about how to add inset maps (and start GH issue to ask people)
• Add simplification for vector shapes
• Calculate number of facets in step1, in order to now the downscale size of rasters
• Create an example external package (to test extendibility) Extending tmap: package management (how?) #565
• Redirect tmap3 code to make it backwards compatible (and check if everything is covered in tmap4) Wrong v3 code translation #861
• How to add additional charts, e.g. histograms? Additional charts (e.g. histograms and marginal rugs) #581
• view: Think about multiple zoom levels: apply scale functions to multiple aggregation levels?
• view: Add/Implement non-standard legends
• view: Think about interaction (e.g. shiny functions): migrate current functions?
• view: Popups: what should/could be included? Also mini charts?
• view: See what recent leaflet add-ons could be used (e.g. leafgl)
• Update tmap_save
• Update tmap_arrage

• Improve running time (ongoing task)
• Improve code documentation (ongoing task)
• Add documentation
• Add examples
• Think about other modes: e.g. rayshare? ggplot (for fun) celium?
• plot add globe view Orthogonal projections #457 upcoming sf will break tmap when adopting s2 #564
• Add global color options (e.g. saturation used in style classic)
• Add global scaling argument
• Re-implement text functions (along.line, auto.placement, remove.overlap)
• tmaptools still needed for tmap?
• Add optional arguments ... to pass arguments to transformation functions (e.g. cartogram)
