Some improvement suggestions

[Sadi58]

First of all, thanks a lot for this useful widget. Here are some suggestions that might hopefully contribute to its further development:

• [ ] For the sake of simplicity, I think we can do without the date and time info on this widget as they are displayed in the system tray anyway - also saving some desktop real estate perhaps.

• [x] When we click on the icon we see a menu like this: City, Country - 10℃. I think it might be better to use something else between the location and temperature here as dash might be mistaken for minus.

• [x] An option to use dark icons in the system tray might please users who have a light bgcolor there.

• [ ] I think a semi-transparent style (e.g. a white foreground on a 50% opaque black background) option would be great who prefer desktop widgets showing the wallpaper under a tinted layer.

• [ ] Another additional feature I would like to suggest is providing option for a second location, probably with less empty space to fit in the same information with the same width but maybe a little more height.
