[Feature Request][UX Improvement] Select All Checkbox to be enabled only if all items are selected.

[samwyzz]

Current behavior

• Click Select all checkbox option
• Deselect any of the selected list items
• Select all checkbox option remains in checked state

Expected Behavior

• Click Select all checkbox option
• Deselect any of the selected list items
• (a) Select all checkbox option should change state to unselected or (b) Select all should be a button without a state and clicking select all should only select all items and not change its state to checked or unchecked.

The reasoning behind this is that:
For the "Select all" checkbox to remain in checked state all list items should be selected,
it is a bit confusing in my opinion that even though all the list items are not selected, the select all checkbox is still active.
One alternative solution is to of course change "select all" to be a button without a checked/unchecked state, and clicking the button should only serve to select all list items.

With sincere thanks
