I wonder what this is from the console.

Actually, it works but it shows an error in Console plus now all my saved projects crash when I reopen them. This is the report:

Heya, the addon is coming along nicely, i bought it as promised 
Was just wondering if there was a way to disable the sub tabs, addons with a lot of tabs can be kind of annoying, especially as your addon doesnt remember which subtabs were open, when switching between addon tabs 
keep it up dude.
animani: uploaded 1.2.3 which should fix the bug you mention. Hope it fixes the crashes too 
getting crashes is always bad, hard to debug and bad for every user…
Way2Close - actually, I’m not very sure what you mean I also don’t like how blender handles subcategories, but what my addon does by now is mainly changing access to the panels.
I won’t be able to respond for 2 days now, due to travels and work.
Hi mate thanks for updating it. I still have the same issue with old projects. I am trying to save new simple projects and they open just fine. The ones I saved yesterday are crashing. Any ideas?
What @Way2Close said it’s something I have been thinking about too. When selecting Main tabs it does not remember which Subtab was selected and it always shows the last Subtab selected from the last Category. So imo it should retain the Subtab selected for each category. So when just selecting Tools it will show for instance “Auto Mirror” because it was the last one you were working with. Otherwise, you always have to click twice. Clicking the main Category and then the Sub-Category. Sometimes you need to move back and forth between 2 different subcategories.

Bought now, thanks.
I have one problem, GroupPro plugin has its own tab in relations.
Would you be able to repair it, please?
Thanks.
Hi everybody,
U upped the version again after some small fixes, especially now the ‘own’ panel drawing seems to be more bullet proof.
animani: I fixed again the bug you report, not sure if that fixes the crashes with the files
jachtarfranko: even if addons create such categories, it should now work so that these get ’ eaten’ by the new ui within a few seconds. I have to do some complex checks if any addons registered later than the tabs addon, and I am not doing them all the time in the script, so it doesn’t eat too much performance. Please let me know if you still have this issue with this latest version.
Really nice work :). But it would be nice if you could make the first sub category as the default one. An example: When you click on the category “Tools” and the sub category “Edit”. Then you click on the category “HardOps”, the sub category “Edit” is still there. It would be nice if the first sub category could be selected automatically, in this example the sub category “Box Cutter”.
I don’t know why, but now when I try it again, I can see the “RetopoFlow” category when I click on the “HardOps” category, before I select a sub category.
pildanovak, thanks for answer, but it doesn’t work well,
maybe there is any mistake,
latest downloaded version 1.24 writes in blender plugin 1.22 version…
Hi, again, there is another fix mini-release 1.2.5 - this mainly should fix drawing order - sometimes some default panels(like physics add buttons) were drawn under tabs, which wasn’t always good. Now these draw on top over tabs always.
jachtarfranko, There might be an issue with the addon, but I don’t have a copy of groupPro addon to fix it. Could you possibly print-screen the console output and show it to me?
pildanovak, thanks for answer, but it doesn’t work well,

latest downloaded version 1.24 writes in blender plugin 1.22 version…
jachtarfranko, so now I understand what happens… The addon hides panel header, which causes it to be detected as more important than it it… This is another very non-standard thing what this addon does. Will have to write exception just for it again.
It’s still unusable for me until you remove the subtabs, there is no need for them in a lot of workflows, I just want access to each addon tab without splitting that into subtabs.
jachtarfranko, just uploaded 1.2.6, just for you and GroupPro…please test if it works
Way2close, and what you’d like instead: to see all panels from 1 category at once? Or should there be tabs for all panels and categories shouldn’t be drawn at all?
which are the workflow cases you are talking about?
Why not to use pinning instead?
I am asking because there are as many opinions as blender users, and it’s still not clear to me.
works well, thanks :o
But are you aware that in your screenshot the layout has these problems:
I can implement it the way that a whole category gets activated when an option I make is on.
“I can implement it the way that a whole category gets activated when an option I make is on.”
Only if it’s not too much trouble, would it be possible to only do that for the ‘T’ panel ? because the rest of the addon is amazing
