Notes are used in different formats:
1. as nodes in the project tree's Notes branch,
2. as nodes in the project tree's Sheets branch, in different Sheets, not yet visualised,
3. as nodes in the project tree's Sheets branch, in different Sheets, visualised,
4. as 'yellow Notes' in open Sheet windows:
5. as (Note) windows:
In the above cases (4) and (5), the format can be changed. When Notes are formatted as 'yellows' in a Sheet window, clicking them will show small black squares at the Note's four corners, that you can drag to change the shape of the Note.
When you open a Note and it turns into a window (case 5), than you can change it as you can any window, by dragging one of its sides or one of its 'splitters' such as the one between the 'From Note' and 'To Note' area's. This format will remain the same as long as you do not close the Sheet or the session as a whole. Next time you open a Note it will have this new format.
The 'Properties' tab of the Note window also allows you to change the Note's color or add an image or icon/logo to its appearance.
