Well this is only for the toolbar really there is like a lot more than this that suffers from this problem. And this table is just to compare things in contrast.
But something that is so local to one thing like the toolbar and not be able to search it because the tool has some random off the wall names makes it very hard to even find it or query it. One would think that searching “tool” would find all tools or writing the name of the tool you could find it, but sadley that does not happen in either case because of the mismatch of names. And the difference between the action and the icon names does not help either. Having some internal logic when giving names to stuff would sort things a lot.
But currently you are able to find things easily if you use the “krita plugin developer tools” that is able to bypass all of this and is one of the best plugins Krita has. And strangely people don’t even talk about it. It is like one of the biggest contributions like ever ever. What I did was just use the search and compare results but even so you need to do more than a couple of tries to find some things even if you know what they are.
