I wish I understood when @dimen is used and when it's not

[Ted C, 2016/09/26 18:05:04]

For me, @dimen is for sharing, otherwise inline and make it easier to read.

+        android:paddingEnd="@dimen/website_settings_popup_button_padding_sides"
+        android:paddingStart="@dimen/website_settings_popup_button_padding_sides"
