I usually have Hide boundary tags and Merge adjacent tags activated. However sometimes you are forced to deactivate them (as CT seems in some cases unable to handle tags in external project properly), and then it looks like this:
Besides the point that this kind of presentation is not really helpful and at least an alternative presentation could mean an improvement (I think I have never mentioned this before), it is rather annoying that all tags in a row (e.g. here from 9 to 14) get deleted when you only want to delete one of them (i.e. they are grouped in deletion).
Another tool automatically transfers all adjacent tags in one, but allows deleting them one by one and inserting characters between them, if necessary.
Could this please be improved?
