Sheet Updates for v1.19! Please enjoy :)
This is a long one with a lot of images, but we are very excited to have Monk Attacks handled at last!
Version 1.19 of the Pathfinder by Roll20 Character sheet introduces two new requested features regarding Weapons/Attacks:
Flurry of Blows for Monk (or monk like) characters
Additional attacks to handle features like Two-Weapon Fighting or Rapid Shot, with one click full-attack action
Flurry of Blows (FoB)
Required: Monk in class name
To add auto calculated FoB attacks to your character, one of your classes needs to have the word “monk” (whatever the casing) in its name, and its level entered.

Using non Core RuleBook classes with monk FoB abilities still need the word “monk” in one class:

Note: if you add the word “monk” afterward character creation, the sheet will not recalculate the base FoB value until Level, BAB, or an ability score is modified.
Adding a FoB attack
A new “Flurry of Blows” option is available in the dropdown list of the first attack modifiers.

Once selected, and with the second attack modifier set to an Ability (generally STR or DEX), the attack bonuses are calculated by the sheet based on your monk level(s), and other classe(s) BABs if applicable.
Clicking the name of the attack will roll a full-attack action:

Scaling with Level
The Flurry of Blows attack bonuses and number scale automatically with the Monk’s class level. Here’s an example with an 18th level Monk:

Additional attacks
Weapons/Attacks can now have up to 3 additional attack rolls (with individual optional damage rolls) to handle features like Two-Weapon Fighting or Rapid Shot, on top of the automatically calculated attack rolls based on the BAB (or other chosen option) of the character.

Two-Weapon fighting examples
For a Level 1 fighter with a Longsword in her mainhand, a Shortsword off-hand and the Two-Weapon Fighting Feat (-2 minus to attack roll for both hands):

Clicking the name of the attack will roll a full-attack action:

Let’s say the proud Test Fighter is now level 12, and has gained the Improved and Greater Two-Weapon Fighting Feats.
The two added additional attacks can be implemented this way:

A full attack roll for Test Fighter now appears like this:

And for Test Fighter's Rapid Shot:

Happy Rolling, Pathfinders!
