SUMMARY Would be nice to have the ability to navigate back or forth to locations. Example 1: User is in cash account and opens credit card account to see some transactions. Then he decides to come back to the cash account. He could use some arrow back to return to the last location(s). Example 2: User is in Current account, he goes to investment account, and then he decides to return to Current account. He could use the arrow back to come back to current account and then arrow forward to go to investment account.
I assume you are using 5.1.x. In versions compiled from git master branch, the ledger is now tabbed, making it trivial to just click the tab to see a different account. Even in 5.1, if the other account you want to see is referenced in the current transaction (such as a transfer or investment transaction) you can right click on the transaction in the ledger, and there should be an entry to "Go to" that other account. I've changed the status of this to "wishlist" as it might be possible to keep a list of which views and tabs have been visited, and be able to move through that list, similar to many browsers work.
