What’s the appriopriate behavior for this "SEE ALL" button? Opening modal window or moving to another tab?

Modal or different tab?

Hello.

I'm designing b2b mobile app.

My main tab, "Overview" consists of sections:

  • recently bought items
  • some recommended products
  • customer's vouchers
  • some statistics

Those sections are in-a-nutshell representations of different tabs. (e.g. Clicking "See all" button in "Recent purchases" section moves you to "Purchases history" tab)

Which behavior of "SEE ALL" button is more appriopriate? I see problems with both solutions:

Option A) Button "SEE ALL" near "Recent purchases" indicates that you will see all of the RECENT purchases. Also search button's behavior in option A is unclear.

Option B) Problem: modal window would double the content that we can already access from the tab view. Problem with search button remains when the user visits the tab.
