https://github.com/FeatherCoin/Feathercoin/commit/3527a5ffa10cda80fb9a2095c6ba394b7cb590ec

src/qt/bitcoingui.cpp

+    QString windowTitle = tr("Feathercoin Core") + " - ";

Name change

+    optionsAction->setStatusTip(tr("Modify configuration options for Feathercoin"));

Message name change

-    openAction = new QAction(QApplication::style()->standardIcon(QStyle::SP_FileIcon), tr("Open &URI..."), this);
-    openAction->setStatusTip(tr("Open a bitcoin: URI or payment request"));

openAction interface change

+    openAction = new QAction(QIcon(":/icons/openurl"), tr("Open &URI..."), this);
+    openAction->setStatusTip(tr("Open a feathercoin: URI or payment request"));

+   showHelpMessageAction->setStatusTip(tr("Show the Feathercoin Core help message to get a list with possible Feathercoin command-line options"));

+       setNumBlocks(clientModel->getNumBlocks());
+       connect(clientModel, SIGNAL(numBlocksChanged(int)), this, SLOT(setNumBlocks(int)));

+        trayIcon->setToolTip(tr("Feathercoin client"));

+    trayIcon->setToolTip(tr("Feathercoin client") + " " + tr("[testnet]"));

 + void BitcoinGUI::setNumBlocks(int count)

Bitcoin code replaced.

   if(count < nTotalBlocks)
+    tooltip = tr("Processed %1 blocks of transaction history.").arg(count);
-    {
-        tooltip = tr("Processed %1 of %2 (estimated) blocks of transaction history.").arg(count).arg(nTotalBlocks);
-    }
-    else
-    {
-     tooltip = tr("Processed %1 blocks of transaction history.").arg(count);

Tooltip interface change?

     // Set icon state: spinning if catching up, tick otherwise
 -    if(secs < 90*60 && count >= nTotalBlocks)
 +    if(secs < 90*60)

If conditions changed.

Third commit

  +

  +    accountReportAction->setToolTip(accountReportAction->statusTip());
  +    accountReportAction->setCheckable(true);
  +    accountReportAction->setShortcut(QKeySequence(Qt::ALT       + Qt::Key_5));
  +    tabGroup->addAction(accountReportAction);    

Tooltips interface change

  +    connect(accountReportAction, SIGNAL(triggered()), this, SLOT(showNormalIfMinimized()));
  +    connect(accountReportAction, SIGNAL(triggered()), this, SLOT(gotoAccountReportPage()));    

Code addition

  +        aboutAction = new QAction(QIcon(":/icons/bitcoin"), tr("&About Feathercoin Core"), this);

 +        aboutAction = new QAction(QIcon(":/icons/bitcoin_testnet"), tr("&About Feathercoin Core"), this);

 +    aboutAction->setStatusTip(tr("Show information about Feathercoin"));

+    signMessageAction->setStatusTip(tr("Sign messages with your Feathercoin addresses to prove you own them"));

 +    verifyMessageAction->setStatusTip(tr("Verify messages to ensure they were signed with specified Feathercoin addresses"));

Interface name change. Bitcoin code replaced

 +    toolbar->addAction(accountReportAction);
 +    accountReportAction->setEnabled(enabled);

Code added

  +void BitcoinGUI::gotoAccountReportPage()
  +{
  +		accountReportAction->setChecked(true);
