Hi
Currently no, I first need to start to work on this case and, if I’m not able to reproduce it, I’ll need more information at this moment
Yes, seems the same than this bug:
If you have additional information or can confirm it occured (or not) with brushes from disabled bundle
Yes, thanks for feedback, I’ve opened a bug
I need more detail about this case
Grum999
Not from a disabled bundle, but I believe it may be related to a conflicted hotkey. I still had 4 and 5 set to canvas rotation, and tried to set them to brushes in Buli.
It’s hard to say when it happens. Definitely every time Krita is restarted, but it has also happened without closing the program. I’ll keep using it and see if I can spot a pattern!
Currently taking a look on it 
I can confirm there’s something, currently I don’t really know what, but I’m starting to get a better view from where the problem occurs.
With Freehand Brush Tool, on my side it took ~0.05s to switch brush
DEBUG: << Stop: setBrushActivated[False//True].00 -- (0.05403829 @+0.05414629)
With Dynamic Brush Tool, on my side it took ~0.29s to switch brush
DEBUG: << Stop: setBrushActivated[False//True].00 -- (0.29191709 @+0.29199147)
It’s not as long as on your side, but hopefully the difference is large enough on my side to be able to try to locate from where the difference come from

@SchrodingerCat I’ve made a version v1.0.0, not officially released yet but all commits are pushed on github repository
You can download & install zip plugin from github code with Import python plugin from web… function
And provide following url https://github.com/Grum999/BuliBrushSwitch/archive/refs/heads/v1.0.0.zip
From my tests, switch time has been reduced from ~0.28s to ~0.011s
Can you tell me if it’s better on your side?
Thanks
Grum999
In fact now it feels much faster, now I no longer see the delay 
Thank you so much! 
Great news 
Grum999
Hello thank you for your plugin
I try to select “keep user modification” on a brush. I select it, change the size but when I switch brushes it return to the default settings. Am I missing something?
Hi
No
There’s a bug
It’s fixed but not released yet
Grum999
Thank you for quick answer, for your info I had the v1.0.0 installed
Which version of v1.0.0?
Does the downloaded version include the last commit?
As v1.0.0 is not yet released, downloaded content from branch will vary according to date/time
Grum999
I downloaded from the link you provided above. I now will wait for the official relase
Thanks
It’s more a question of “when” than “where” in our case.
The provided link is a link to branch content.
If you’ve downloaded it before I’ve made the bug fix commit, the option won’t work.
If you’ve downloaded it after the bug fix has been pushed in repository, normally it should work; if not, there’s another problem then
Grum999
Doing some additional tests, it seems that it’s not totally fixed… 
Need to check it…

I am using Krita 5.1.3 on Win10.
Using the latest version of this script version, an error occurred when starting Krita.
It has been a long time since I enabled Buli Brush Switch, so it is not likely that the error occurred because I used the latest version of Krita.
It appears to be caused by deleting a brush preset that was previously registered in Buli Brush Switch, but I don’t know how to work around it. I keep getting the same error message even after re-installing the script.

Hi @dk8
Thanks for feedback
This is like this bug, related to disabled bundles/preset
Bug is fixed and available in repository, but not yet released (I’m currently in very slow mode code mode 
)
You can follow instructions provided here to get the dev version of future 1.0.0 release:
Grum999
I did not properly check the latest contents. My apologies.
I got the following error when installing 1.0.0. The content has changed, so I am reporting it just in case.

No worries
This one is weird, I need to dig.
Can you try:
C:\Users\daini\AppData\Local\krita-plugin-bulibrushswitchrc.json to C:\Users\daini\AppData\Local\krita-plugin-bulibrushswitchrc.json.backupDid you still have the error?
Grum999
After following the instructions, the error stopped and the functionality became usable. Thank you.
Great!
Can you show me content of .json.backup file?
I think it’s related to problem with deactivated bundles/preset; I fixed the problem for installed plugin but it seems I didn’t think to check what happen on an install for which an old configuration file what still here
Grum999
This is it.
