RH2020 entering map ids doesn't work very well

The MAP FILES editor of RH2020 does not work very well. Creating MAP IDs from the topics with automatic MAP NO creation is no problem, but editing the MAP FILE is almost impossible. I want to do the following:

- Changing the MAP NO of topics to get topics of a chapter in a certain range, e.g. chapter 1 with map ids 1xx, chapter 2 with map ids 2xx, etc

- Adding MAP NO for topics that do not exist but that could be required in the future. E.g. the text for a dialog with 3 parts is now small enough for 1 topic, but in the future I could make 3 topics of it. I want already to define the MAP NOs now, so that the software developers can already include these NOs to call the help. When the help is extended later, then they don't have to change the software anymore. For this, I drag the same topic several times to the map list, each with another MAP NO and rename the MAP ID.

These are the problems that I have encountered while trying to edit the map file:

- Renaming one MAP ID simultaneously starts to rename another one!

- Renaming a MAP ID sudenly erases the typed text if is is equal to an existing MAP ID. I was not yet finished typing!

- When you click a MAP ID or MAP NO to edit it, then the pointer must stay on the field or you can't enter anything

- When you rename a MAP ID that already exists, you get an error (which is ok) but MAP ID is erased. It would be better to leave the new name and allow to correct it. Now one has to retype it completely.

- RH seems to remember MAP IDs that have been entered before and while such MAP ID no longer exists, it still says that it is already used.

Note:

It is not possible to edit the .h file outside RH like with RH10. It is only possible to export it. An import is required!

I did not yet succeed to create the map file the way I like. I have been trying to get it right for too long now.
