This is indeed a percentage of the use cases of maybe only 5 %, but the dialogue box for TMs offers the possibility to set read-only (RO) for newly created TMs. This shouldn't be the case, should it?
I do not think there should be an easier way to switch between RO and not-RO, this is fine as it is.
And: A grateful note in the concerned Solutions articles would be easier to realize.
You underestimate the intelligence of CafeTran users. If they choose read-only, they know it is read-only - and not the other way around. :)
