There are some of my annoyances with the new SourceTree Windows App:

• Text rendering is horrible. Every bit of every text is blurry. I know, it's WPF but i also know Visual Studio's latest versions (at least GUI parts) written in WPF and doesn't suck that much.
• When i right click on the left pane, i want to see which item i've right clicked. It should be selected. But instead "File status" is selected momentarily. This also sucks.
• Escape key does not work when i do something requires a git command to be executed. For instance after i switch a branch, i cannot press escape to dismiss that popup-ish thing.
• I can tab to anything while the popup is showing up. I can focus on files in "Log/History" tab and i can switch to see diffs of other files. Also upper tab bar is focusable. It shows a big dashed rectangle around tab bar. Keyboard navigation is a mess.
• Tab bar hover animation is bouncy. Close button and tab height have a bouncy animation but tab text have only ease in animation.
• Whole application becomes unresponsive sometimes.
