When adding a node under 8.5 in System Manager there was a drop down box that included all of the community strings that were in use/ had been used before. This was nice because the people that were entering nodes did not have to look up the community strings every time a node was added or commit the community string to memory.
Now in 9.1 when adding a node via the web, there is no drop down box only a text field to manually enter the community string. For those that may only enter nodes occasionally or for those that have a bad memory (me) a drop down would be SUPER helpful.
I can clarify further if this dose not make sense.
It's something we're considering for a future release.
