Good news!

R3 is close, mostly just tidying stuff up now. I'm aiming to get the full release out ASAP. One new thing to note is the slightly updated icon. Actually, there are three; blue for releases, red for development previews (like this one!!) and yellow for CI/canary builds:

Now, onto this preview build...

New features

• Win+F2 toggles hiding and showing the system tray in dynamic/split mode. In the future this might be customisable.
• Split mode is now supported in Windows 10 (for horizontal taskbars only at the moment). It's like dynamic mode, except not dynamic. The taskbar can be resized manually with a grabhandle, however. I'll be working to bring a full dynamic mode to Windows 10 in the future, it's just a bit more difficult on 10 due to its inferior taskbar.
• Experimental compatibility with TranslucentTB (this requires an experimental build of TTB so it won't work for you yet but trust me it'll mostly work!)
• Dynamically adjusting sliders for margin and corner radius

Fixes & improvements

• Flickering caused by tray resizing no longer occurs
• Autohide should now work with dynamic/split mode
• Dynamic mode should no longer randomly resize as much (not quite perfect yet, notably on secondary monitors)
• Not as many random crashes probably
• Replaced "RTB" strings with "RoundedTB"
• A bunch of minor fixes

Known issues

• Taskbar still flickers occasionally
• Autohide with dynamic mode is really ugly
• Secondary taskbars may vanish on occasion - to resolve, move a window to or from that monitor
• Dynamic mode/split mode currently only works on horizontal taskbars
• Independent margin controls are disabled as they don't work
• Probably loads of tiny bugs I'm not aware of

Feel free to let me know of any bugs you encounter by filing an issue. Just make sure you tag the issue as prerelease!

Thanks for using RoundedTB, and sorry for the delay; not too much longer now! If you want to keep up-to-date with how I'm getting on, feel free to join the RoundedTB Discord server. If you want to try out canary versions that are even more experimental than this, you can always use this link to get whatever the absolute-latest build is.
