Fixed

• Editing a location now tells you when the new name is empty or already in use, instead of silently discarding your changes.
• The tray text format dialog now warns you about unknown placeholders or unbalanced braces before saving, so a typo like {tmp} can't quietly end up in your tray tooltip.
• Closing the Add or Edit Location dialog while a search or current-location detection is still running no longer risks a crash.
• Weather history's "Today vs Yesterday" section now reads naturally when both days have the same temperature, instead of "is 0.0°F about the same than yesterday".
