I’ve just installed TDM3 Beta and started testing this tool. Looks great!
First petty issues I have found are:
There are small localization misprints in the dialog box Export to Graphic File, Tab JPEG - “bity+bitu” instead of “bits” (see attachement).
Editing attributes of entities you have possibility to select more than one attribute, but when you try to make multiple changes - all actions are applied just on the attribute which has the cursor set (eg. the first or the last you have pointed selecting multiple attributes whith SHIFT key). This is a little bit confusing - you couldn’t select more than one attribute earlier in TDM 2.
