This just started happening a few minutes ago.  I updated to 7TT 5.5 a couple days ago. 

Without providing any stimulus to the task bar, all of a sudden my windows on the taskbar just rearranged themselves.  The order of all buttons within groups were preserved, but two groups just magically rearranged themselves to an order I've never set them to.  My mouse cursor was nowhere near the taskbar when this happened.

After I moved the groups back to the order they were in before, they rearranged themselves again seconds later to the way they were before I restored their original order the first time.

There must be other conditions involved here, because it's not doing it anymore.  It did it like three times in a row within seconds of each other.  After that, I force-closed 7TT from Task Manager and re-opened it.  After I re-opened it, the main 7TT window was acting weird.  It would disappear for a split-second and immediately reappear.  It did that a few times as well, spaced a couple seconds apart each time.

My taskbar is oriented vertically.  I'm using 10 Pro 1709.  This is the only program exhibiting strange behavior.  I don't really know how to quantify this any better at the moment.  Are there logs somewhere?  I can't find any in ...\Appdata\Roaming.

I can only fit 19 apps in each taskbar row.  After that Windows adds another row and has up/down arrows on the right side I can use to scroll between rows.  Dragging apps around inside a row works great, but I can't figure out how to drag them between rows.  It would be nice if I could drag them to the up or down arrow, hover there while it goes up/down through the rows (either variable speed or maybe 2 per second), then drag & drop it where I want inside the row.  Thank you.

If the file explorer is the first item in the taskbar, it is moved to the last position every time the 7+tt is launched/closed. If the file explorer is the second or third item (or any other position), this issue does not happen.

e.g. I have:

    explorer | edge | excel | word

I launch 7+tt or close 7+tt or change 'Combining' settings or use taskbar inspector:

    edge | excel | word | explorer

I started using your app a few versions ago and this issue has always happened.

At this moment we could only change the items order side-by-side like 
[chrome] [firefox][opera][MS word][Notepad]...


I would like to choose the line of the items.
eg:

[chrome] [firefox][opera]
[MS word][Notepad]
[other][other][other] [other]

-- this idea is for horizontal positioned taskbars, but might be extended to vertical also --

theres always the tendency of buttons to stick to the left

you cannot say a button to stay at a specific position on the taskbar!!

i want for example my excel button to stay at 5 cm distance to the rightmost, or say chrome button to stay always at the centre, etc.

- then the combined/gruoped buttons might also take their place beginning at that specific position...

isn't it possibel?

The seconds will only show if I toggle the option off/on again.

I tried to find a registry tweak or program or something to reduce the delay between hovering on a taskbar button and showing the tooltip (there's a very short delay for the preview, which I think can be adjusted, and then another ~1 second delay before the tooltip appears above the thumbnail) but wasn't able to find anything except a bunch of other people trying to figure out the same thing. I wonder if this is something 7+TT could do since it hooks into the system, in which case that would be a really nice feature. Another thing some people were trying to do, but that doesn't seem possible through "normal" means, is adjusting the text/font size of the tooltips.

I think there should be a button in the UI for advanced settings, or maybe within the settings window. I've been using this program for years and didn't even realize it had those extra capabilities. I realize I would have known had I read the help file, but being a relatively advanced user (hence the desire to use advanced settings) I never needed to and so never bothered. It seems ironic that those who are most likely to want them are those that are least likely to look at help and discover their existence. If the reason for burying them is so basic users don't screw stuff up, there could just be a warning when entering into them and the option for them to be hidden (so someone setting it up for someone else could hide them).
