In Lotus Notes 7.x the ability to “Save Window State” (File > Save Window State) was introduced to allow users to have certain databases available to them on startup.
This ability is available in Lotus Notes 8.5.x but is set up a little differently. Now you must bookmark the databases you wish to appear automatically at startup in a special “Startup” folder.
To do this, right click on the open tab and select “Create Bookmark”
Then select the “Startup” Bookmark folder located under “More Bookmarks”
If you want ONLY the bookmarks in the startup folder to show up when the Lotus Notes Client starts, then go to Files – Preferences – Windows and Themes and DESELECT the “On restart, reopen any tabs that were open when I closed the client”.
If you leave this checked, all tabs that were open will show up on restart PLUS the items in your startup folder. So, even if you had closed any of the tabs represented in the startup folder they will be available when the client starts as expected.
