Is there a way to do one of these things in the Web Client?

• Create a link (not custom tab) to an external page (not an embedded page like a tab) and have that link use the entry ID of the document then open in a new tab.
• Create a custom button that opens a URL in another tab like the item above.
• Use Connector to pull information from the browser URL instead the advanced details area to get the Entry ID. 

Why do I need this?  We have a tool for our customers to use for signing documents in the Laserfiche Repository (in person with a sig pad or remotely).  When using the Windows Client, we are able to programmatically place a button in the Windows Client so that our customers can click a button to open that Laserfiche Document directly in our browser tool.  I would like to see if there is a way to add a button, link, or connector button to give the same level of functionality to our Web Client customers.  

You may ask, why not just create a custom tab?  When our webpage loads there are a few pages that run, like checking for a sigpad and authentication, that causes the tab to leave the Web Client and open on its own.  Then when you go back to the Web Client and open a document, since the custom tab is still open by default, it leaves the document immediately and opens our page directly.  I just want to see if there is a way to open a URL in a new tab that has the Laserfiche Entry ID of the document in it without going to our developers.   

Also, I know I could just create a blank URL that only has a link to our tool and embed that so it opens in a new tab, but I would rather have something a little more elegant.
