Version 2.0 update, featuring popup Formation Toolbars...
The attachment FormationsPopup.jpg is no longer available
Attackmarch replaces the Column by Division formation, the Formations button replaces attackmarch. Column by Division is now included in the pop up formations window.
These toolbars (eight total - levels 5 and 4, Allied infantry, French infantry, cavalry, and artillery) contain most of the formations available in the Drills.csv file. Also additional formations are included.
Info:
1) To differentiate between the three arms, infantry, cavalry, and artillery, the correlating menu tabs must be selected. Menu tabs turn brown when selected. The game opens with Infantry as the default selection.
2) Brigade level and above are included only. Battalion level may be included later if lobbied for.
3) Some formations are duplicated from the toolbar to fix stock inconsistencies, others are duplicated more or less for place holders. The latter can be replaced or removed as per community feedback, IOW I went with orderly appearance rather than practicality in some cases.
4) Click out to close unused formation window.
5) Corps level formations added to the toolbar.
Redesign:
1) Brigade level battalion squares now line up in a checkerboard fashion, as historically.
2) French Column by Line battalion level formations maintain their '3 rows deep' regardless of strength or sprite ratio.
3) Artillery double line, second line adjusted to front row gaps.
As mentioned in an earlier post, please feel free to make suggestions and provide formations you feel the game and community can benefit from.

Thanks again for all the support of this mod.
