SUMMARY

There is no way to disambiguate among identically named towns/villages when adding locations to kweather.

STEPS TO REPRODUCE
1. Try adding Zachełmie

OBSERVED RESULT

There are two entries for "Zachełmie | Poland", corresponding to two real villages with the same name hundreds of kilometers apart. There is no way to tell them apart in kweather. If you add one, the UI provides no information that could help to know whether you chose the right one. Basically the only way is to add one provisionally, then watch the weather outside, and if it's poorly correlated with what kweather says, it's probably the wrong one.

EXPECTED RESULT

There should be a map widget embedded in the location search dialog, showing the geographical vicinity of the chosen location. Additionally, the main UI should have a button to show the current location on a map. Displaying latitude and longitute somewhere wouldn't harm either.
