- New status bar control shows the current Unit of Display. When clicked (left,or right button) it shows a context menu that allows the user to switch the current Unit of Display (BTC, mBTC, uBTC) - Recent Requests and Transaction Table headers are now updated when unit of display is changed, because their "Amount" column now displays the current unit of display. - Takes care of issue #3970 Units in transaction export csv file. - Small refactors for reusability. - Demo Video https://www.youtube.com/watch?v=wwcr0Yh68go&list=UUG3jF2hgofmLWP0tRPisQAQ - changes after Diapolo's feedback. Have not been able to build after last pool, issues with boost on MacOSX, will test on Ubuntu these changes. - removed return statement on switch - renamed onDisplayUnitsChanged(int) to updateDisplayUnit(int) - now getAmountColumnTitle(int unit) takes a simple unit parameter. moved to BitcoinUnits.
