A few new dictionaries are now included in the DPR: Pali roots via the Saddanidhi, Sanskrit dictionary using the colossal Monier-Williams text, and Sanskrit roots, using a text based on Whitney’s volume. The MW dictionary is huge of course; I got it down to 90MB unpacked, but decided it was still too much for the main archive. So, there is now yet another extension you need to download to experience the full range of DPR goodness:
Once you’ve installed this, you will be able to use the two sanskrit dictionaries via the DPR. There is no way to use them without the DPR, so you still need the DPR to use them and, as a result, the Myanmar extension as well. Downloads are in the sidebar, as always.
