In Bookmap 7.1, the program allowed scaling to a smaller high res UI, from changing the properties of the program in compatibility settings on Windows. According to support, this was more of an exploitation of Java 8's inability to handle scaling correctly.
It would be nice to have an option in Bookmap 7.2 to scale the resolution so that one may have more heatmap space and smaller text, really helps when sectioning off a monitor to 4 Bookmap windows.
Allow scaling in Beta 7.2
Re: Allow scaling in Beta 7.2
It seems that the public v7.3 version still has this resolution/scaling issue.
