Concise description:
Specifics:
This will improve the following aspects of the site:
- Blank values in the first row of selection lists
Specifics:
- Code a blank value in the first row of all selection lists so there is no default value.
This will improve the following aspects of the site:
- this will help prevent players, especially novice players, from accidentally attacking or fortifying to or from the wrong territory by requiring them to select a value in the list.
- The blank value can have a text label that provides a message such as "Please select" or something to instruct the player to select from the list since some players may think a blank means an empty list.
- May speed up the selection process allowing for faster actions which can be crucial in freestyle games if turns are taken simultaneously with other players.
