I faced the same problem in Blender 2.92-rc too. problem is this. when object turns to Library override, Blender keeps 2 version of the object. the link of the original one and mirrored local one. Inside the scene only local one detectable but drive can see the both.
Drive detects the target by name and this cause some time get linked one and some time the local one.

@Brendon Murphy (meta-androcto)
Are you prepared to maintain this addon in Blender during 2.8 series? yes
Are you familiar with the git system? Not yet but its most be easy
Are you prepared to handle bug reports? Yeap
I' would start a BA forum task..... > Good idea, thank you.

But this tool just appears when more then one items selected other ways "Rename active items" is appear.
Yeah, Ideas about Cap sensitive or upper, lower case is cool and I will add that functions too.
@William Reynish (billreynish)
No matter how, internal or external add-on. Matter is User has this ability to use this tool.
I think this most be fine to see Users feed backs, and update it until become almost perfect to fit in Blender.
My goal is learn how to contribute with Blender Team. This is just a start with a very simple tool.

OK, almost done.

Sorry for my long delay, I just spend all of my time on other add-on. I will complete this one soon as possible.

I do not think its a problem, all standard tools works on selection.
e.g. Delete, Transform , Edit mode toggle, even Mesh editing tools.
if you want move only one object you have to de-select the others. or set one object to edit mode you have to de-select others. and there is no reason to add different short cuts for single and multiple mode.

Sorry it toke long time I`m working on an add-on in the same time too.
I know you are buzzy but this is first time I`m using Github. And maybe I do a mistake and I don’t want to make a treble for you. For other tools I wrote this proses will be too shot and easy. For now I faced with many questions that confusing me.
Is this right? I have to make a diff file between the first file I sent and the edited new version of the same file as a *.diff file, that made by “git diff” command. And send it from “Create Diff” page. ?

@William Reynish (billreynish) It`s OK. I`ll read and create a patch. thank you.

I tried two method with hashtags.

• Set Name
• Find & Replace
• Clean (remove unneeded numbers, make numbering consistent, trim whitespace, ...)
• Trim (at start, at end, max length)

The context rename panel still can be simple the batch rename panel open just when more than one object selected.

basename.#### looks simple but always start from 0 or 1 and have not control to continue renaming from specific number but having control on number of digits is good idea.
I can add a automatic numbering option, that detect the last object in same name and continue renaming from that number.
