SharePoint 2013 users only see custom list and document lists that they uniquely created

Question

In my first SharePoint 2013 project, I want to create a view where users can only see their own files that they generated. I think I know how to create this view when the list is associated with the 'Documents; folder. However I have created several custom
lists where I can only see these items when I am on the navigation pane to the right and the unique custom lists are listed under 'recent'.
Let me know if you can answer any of the following questions:
1. When on the main SharePoint website, can lists be displayed in other locations than what I just listed? If so, where would I see these other lists?
2. I would like to include the custom lists that are located in the 'recent' navigation pane as a view that only I can use. This would be based upon userid. If this is possible,  how would you combine the lists lists in the same view? If this is not possible,
how would you set a view just for the lists listed under the 'recent' section?
3. The content approval solution under versioning settings of a library to restrict the documents to only ones that the user created (and also Approver rights).  Then if they create a new view they still won't see the documents that were not created by
them. What about custom lists that are not in the documents area but are in the 'recent' area? Would this restrict users to see only items that they created?
4. Item level Permissions in advance settings solve this problem for the list in the document area and the custom list in the recent area? If so, how would you setup these values?

Answer 1

As it turns out the, setting Item-Level Permissions in a library is fully supported with PowerShell!
The PowerShell commands for changing this are very simple:
$web = Get-SPWeb http://YourSite/
$list = $web.Lists[“Your Document Library Name”]
$list.ReadSecurity = 2
$list.Update()
$web.Dispose()
Note the 3rd line which is where you determine the value for this setting using the following values:
1 = “Read all items”
2 = “Read items that were created by the user”
If you wish to modify the values for Create and Edit access instead, replace .ReadSecurity with .WriteSecurity with
the following values:
1 = “Create and edit All items”
2 = “Create items and edit items that were created by the user”
4 = “None”
For example:
$web = Get-SPWeb http://YourSite/
$list = $web.Lists[“Your Document Library Name”]
$list.WriteSecurity = 2
$list.Update()
$web.Dispose()
