Just wanted to point two errors about the spanish localization in the UWP app:
When right clicking an entry inside the folders' or favorites' section it should show 'Eliminar', but shows 'Remover' instead (which means 'stir' in english, not 'remove'). In the main section appears correctly.
In the spanish language there is no capitalization in titles and such as there is in english. All of them are capitalized and this is just wrong. For example:
'Tarjeta de Crédito' should be 'Tarjeta de crédito'
'Iniciar Sesión' should be 'Iniciar sesión'
Otherwise the app keeps getting better and better, keep up the good work with the UWP!
