Feedback for CiviCRM 1.9.beta.11750.

I converted a working 1.8 setup to 1.9, there were no errors. I did some tests with the following result:

1
There are a few screens were the content goes out of the content page. For example :
civicrm/contact/search/basic?reset=1
civicrm/contact/search/advanced?reset=1
civicrm/group?reset=1

2
I made a costum field with 'costum data' newsletter radiofield yes/no
I made 1 (test) member of with the newsletter on Yes
I made a smart groep for a newsletter on Yes
When I select 'members' of this smart group in the group page civicrm/group?reset=1 the (test) member is not shown
When I select 'edit smart group criteria for newsletter ..' the member is found as group member!!
Because of item 1 there is no button on civicrm/contact/search/basic?reset=1 so I can not test this in the search page

3
The status of mailings transferred from v1.8 to 1.9 are not shown on the report page.
For example civicrm/mailing/report?xxxxxxx
Because of that, there is a Delivery has not yet begun for these (older) mailings.

4
Re using a mailing (transferred from V1.8 to 1.9) looks good till step 3 Mailing Content.
With Compose ons screen:
The text message shows the correct used text
The HTML message box is empty
The original V1.8 mailing was in Text and HTML

5
After filling in the HTML box (see item 4) the newsletter is send to the smart group members
Test mail and mailing to smartgroup goes correct.
The mailing is also received by the smart group member (!!), despite of the problems of item 2.

6
Testing report if the newsletter:
Recipient included: not shown (item 2 related)
Delevery summery: looks ok. Because of the setup of my imap to soap (working site) I could not test unsubscribe and opt out.

7
Q: I thougt there is a HTTP opt-out/unsubscribe option, discussed in http://issues.civicrm.org/jira/browse/CRM-2233.
I could not find information how to setup and how to use this. Please help.
