I must weigh in here. I'll be surprised if the hundredths place has reasonable significance in any protein crystal structure. Indeed, the tenths decimal place is likely weak in many structures. Remember also that in a distance measurement the uncertainty doubles.

We do a disservice to the novice user to present distances to 3 decimal places (OK, even to many non-novice users). It gives them an improper sense of the data. 

I would prefer a default of 1 decimal place for Angstroms.

If a user selects 3 decimal places, an alert should pop up asking them if they know what they're doing   ;)

P.S.  does anyone really believe that gas pumps can measure your purchase to 0.001 gallons (0.8 tsp; 4 mL)?

Is there a way to limit the number of decimal places shown next to
monitor lines? I would like only one (can't find this documented, if
is please let me know).

There is currently no mechanism to support this.

If this is not too difficult to implement, I would find it very useful
to be able to round off the decimals to one place. In cases where you
are indicating several nearby measurements in one structure, they wind
up obscuring the structure itself. In addition, at least for angstroms
I think the additional decimal places may not be significant. Any hope
for this feature request?
