[dannycohen]

1. Need to design and update the information "i" icon
2. See images below

This also applies to the re-design of the Options dialog. see #208

@dannycohen @sergioc I think also a Warning sign as well. It will be displayed if you can not connect to SC.

@sergioc - thanks!

@HEskandari - Can you implement the above ?

[HEskandari]

@dannycohen @sergioc I have done the changes above. Call me a nitpicker but the following icons are still not properly designed:

-Save and export icons in the main menu. Currently disabled, but we could hide these items anyway because the functionality does not exist yet.
-Options menu item under View menu.
-Retry message on the context menu for the failed messages.

If you think any of the existing icons from this page can be used for any of the above, just let me know the name.

@HEskandari - excellent nitpicking! Opening another GH Issue for those and closing this one as done.
+1 on updating removing them.
Thanks!

@dannycohen found two more, there's the Add/Remove buttons from the list in the Options dialog, used for managing recently used lists (ServiceControl, Search queries, etc.).

@HEskandari - thanks! Please add these to #241
