[done] request: make working with larger landmark lists easier (check/uncheck all, multi-select, etc.)

[theksmith]

issue: lists of more than a few items within the Displayed Landmarks and Explore Landmarks features are difficult to work with.

- within Displayed Landmarks, there is no way to easily select or deselect ALL items within the list. this makes it difficult to quickly show only a few desired items from a longer list.

- within Explore Landmarks, there is no way to select a portion of a list (multi-select) in order to Cut/Copy/Delete multiple items at once. this makes it difficult to manage the contents of files that contain multiple tracks or waypoints. it is especially a problem when trying to organize imported GPX files that were then re-exported (you quickly end up with multiple nested folders inside a file), or to merge saved tracks & waypoints with existing landmark files.


proposed solutions:

1) within the Displayed Landmarks feature, modify the menu that is opened by the "3 vertical dots" button that shows on the the right side above any list (the one with the "Sort By" options): please consider adding "Check All" and "Uncheck All" options to this menu.

2) within the Explore Landmarks feature, again modify the menu that is opened by the "3 vertical dots" button above lists:

- add a menu option to enter "Multi-select Mode" which would show checkboxes next to each item in the list. once selected, this menu item would change to "Cancel Multi-select" in order to stop showing the select checkboxes.

- also add menu options for "Check All", "Uncheck All", "Copy Checked", "Cut Checked", and "Delete Checked". these options would be disabled or hidden when not in multi-select mode.


thanks in advance for considering these enhancements!

Hi again,
I'll do my best to add multi-selection as soon as possible.
This will be one of my priority for the next version (the one after 2.0.4 currently under tests).
For now, I've added the select/unselect all action in the displayed landmarks (1).

thanks!
