Not likely to be added to 7+ Taskbar Tweaker. First, it's not directly related to taskbar tweaking, it's more about leveraging an existing functionality. Second, there are several other programs which provide similar functionality.

It's not that I don't think it is an appropriate addition to 7+ Taskbar Tweaker. It's just that such an addition is time consuming: research (unknown amount of time), implementation, help files. No offense, but I'm reluctant to do this work for a fix which is going to benefit one or two users. I've done this in the past, and in retrospect it's not a good use of my time. I'll keep your suggestion in mind though, and if I see that more people have this problem, I might look at it one day.

I'm not familiar of this problem. Why do you think many people have it?

You might be able to adapt my taskbar-resize code, which currently only supports a vertical taskbar.

Currently there's one option regarding transparency in 7+ Taskbar Tweaker, one which disables it. You can find it under the advanced options.

I'm glad that it works now.

Hi MtKenSan,

If this is not possible, would it be possible to provide an explanation?

It is possible, as pretty much everything is. But I don't have infinite time, and different tasks have different priorities for me. You're not the first user to ask about theming customization. Currently 7+ Taskbar Tweaker doesn't provide such functionality at all, and I'm not sure it ever will. It's a broad topic - you want to add some "depth" to the buttons, another user might want to remove the line under the buttons, a third user might want to change the color of the taskbar, or change the start button image, etc. etc.

In fact, I haven't researched it at all, so I, just like you, am not quite sure how DWM works or what's the best way to change the appearance of the taskbar. The tweaks I implemented are a bit different, most of them are not about the visual appearance. I might research this topic one day, but currently it's not something I'm planning to do.

Please specify the exact error message that you're getting, including the number in the parentheses and the second line of the message text.

There's an advanced option in the tweaker for this. Please see the following answer that somebody wrote on Super User:

I'm not going to move it at least because it will require a migration of the current issues, and it usually turns out to be ugly (example: imported from Google Code). It also requires time investment, and I don't feel it's a good use of my time.

And even without the import issue, I don't see a benefit in using GitHub issues instead of UserEcho. Perhaps because GitHub is more popular, but on the other hand, it's developer oriented and less average-user friendly. And not only developers report issues about 7+ Taskbar Tweaker.
