Suggestion, that may be difficult to execute, but still, i'll leave it.
"Unusual shape" category should be devided into two subcategories: variants with none-rectangular cells (triangular, pentagonal, etc.) and variants with unusual connection and/or arrangement of rectangular cells (like cylindrical; well, maybe, not only rectangular - e. g. cylinrical hexagonal chess will belong to both categories).
One aspect - for new people at chess variants, who are only getting familiarized with CVs, these categories are probably more comfortable to be in one category, but for these, who already got plunged into world of CVs, this division will be helpfull for searching chess variants.
