Things I’m going to do are more of a technical claim.
I’m working on another border-style, which is very time consuming. Like in the map for 1941 I prefer the 3-line border style, consisting of non bezier-points (bezier points are editable by adding vectors; by doing so straight lines can be transformed into curved ones). The borders in the map for 1942 are consisting of bezier-points. Eventually any line, any curve has to be transformed. For this work, the correctness of the border topology is of most importance (…again, thank you for your feedback!). The 3-line border style is demanding, you have to edit 2 lines in any point of the line to fit the origin line, it’s not possible to just copy and paste a line. This takes a lot of time.
Another step is to introduce “written” territory names. Right now the names of the territories are “curves”. At fourth, new layers will be introduced (e.g. house rule layers for another IPC assignment to the territories, alternative or additional roundels). Most things will make no significant change in comparisson to the actual map. Concerning the time line: given the experience I gained up to now, this all will need several hours a day for 2 up to 3 weeks.
