There are a few issues which I'm aware of ever since .59 for which I've been uploading temporary fixes, as they are not in the script code. Failing to board the ship may be due to a webwalker error (can be seen in the logger if that's the case). For the ship part I uploaded a fix 2 days ago but the SDN still hasn't updated, it will take take ships from another place as the webwalker in .68 seems to have some error with the Port Sarim ship.
There is a DMM button on the GUI which was requested about a month ago by a user, I have not tested it myself as I never played DMM, but all it does is ignore teleports. In order to use it, you are required to have the required items as there is no Grand Exchange
You have to create a gear preset using the Gear Editor tab. Set your gear and preferred attack style in game then press "Load Gear". The gear should now be displayed on the GUI including the attack style, marked as FIRST, SECOND, THIRD, FOURTH and FIFTH (for magic). They are in the same order as they appear in the combat tab, FIRST usually being accurate, SECOND aggressive, THIRD controlled, FOURTH defensive. After you are done with the preset, press "Save Preset" and then from the main window where you add quests to your quest list, select the gear preset (initially, it will be set to the "DEFAULT" preset)
