The current workflow to get from a transaction search to the interaction details is:

1. Fundraising Transactions search by transaction id

2. Click on constituent name

3. Go to Interactions tab

4. Find the same donation from step 1

5. Click on the subject to get to the interaction/transaction details.

A link to the interaction details would make a lot of sense and avoid extra steps to re-locate the same transaction as in the original transaction search results.
