Feature request: Enhancement to Show on Map tool

[ianb888]

I can see that the Show on Map tools supports several formats, but it currently lacks support for Maidenhead Locators.

Maidenhead Locator System

Because the Maidenhead Locator system describes an area, rather than a specific point, then when converting between formats then it would make sense to use the centre point as the main co-ordinate. This would be a useful feature for many users, in particular amateur radio operators.

It would also be useful to include this in the Convert co-ordinate format tool.
