Are the icons blurry all the time, or does it happen at some point? I noticed that this happens sometimes when the resolution or the DPI changes.

I believe that both will work, but C:\Program Files is the more correct option.

Is there a similar product I can use to re-arrange taskbar tabs?

I don't think so. I'm not familiar with any alternative for Windows 7 and up.

Several antiviruses disallow running apps from the AppData folder. You can try the following:
1. Try installing the tweaker to the Program Files folder. You need to run the installer as administrator and choose the Program Files folder manually during installation.
2. Try the portable version of the tweaker. See the FAQ for instructions of extracting the portable version.

I tried to reproduce it with Notepad both with a click and a mouse wheel, both on Windows 8 and Windows 10. I couldn't reproduce this.

Just tell me how you customized the left click. If you're saying that it happens without you customizing the left click, then it probably happens when the tweaker is not running, too. Is that right?

Attaching the relevant screenshots:

As far as I understand, you'd like to be able to have this:

Let me know if I misunderstood.

What's your setup? How can I reproduce this?

There are no non-advanced options related to the left click. So please provide your relevant advanced options, and I'll see if I can reproduce it on my computer.

I couldn't reproduce it. What I tried:

• Open and maximize Notepad.
• Minimize it.
• Set "Middle click" to "Switch to".
• Double click on the Notepad taskbar item with the middle mouse button. (1)
• Minimize Notepad again.
• Check "Minimize/restore when mouse is over: Taskbar buttons".
• Restore Notepad by scrolling up aggressively. (2)

During my testing, in steps (1) and (2) (and in general) Notepad never became restored, only minimized or maximized.

I mean if I cycle through windows I'll end up with all windows restored, cuz it's restores ech window one by one.
