+            - UI/UX improvements in proxy manager: <br />
+            &nbsp;&nbsp;&nbsp;&nbsp;- Favourite button is placed on proxy item<br />
+            &nbsp;&nbsp;&nbsp;&nbsp;- Pressing 'DEL' now removes selected proxy<br />
+            &nbsp;&nbsp;&nbsp;&nbsp;- After proxy is removed next to it is selected (allows to remove proxies quickly)<br />
+            &nbsp;&nbsp;&nbsp;&nbsp;- Empty lines on import now ignored (previously entire import was cancelling)<br />
