Idea: Aligning reaction arrows horizontallyDone

Hi, I’m really enjoying MolDraw! Is there a way to align multiple reaction arrows so they’re all at the same height? If this is already possible, could you explain how to do it? Otherwise, it would be a useful feature for keeping reaction schemes tidy. Thanks for all your work on the site!

Bug: some elements after exporting in svg are not aligned

Hi, I’ve noticed that some letters in text labels and the hydrogen labels in amine groups shift slightly upwards when I export the drawing. Thanks for your help!

Bug: “Filled” arrowheads are drawn as “Open”Done

Hi, I’m having an issue with arrowhead styles. The arrowhead remains open, even though the panel shows “Filled”, when I reopen the Arrow tool, the setting also returns to “Open”. This happens repeatedly with newly drawn arrows, the attached screenshot shows “Filled” selected alongside arrows with open heads. Could you check whether this is a bug or whether there’s another setting I need to change? Thanks!

Explicit H's

When the "H+" button is used, it adds explicit hydrogens, BUT there is no way to remove them afterwards (like an "H-" option). In the options menu (gear icon), I try using the "Show explicit H labels" option to remove the explicit hydrogens, but they do not disappear.

Protonation statesDone

Hello, Would it be possible to add a function similar to the pKa tool in MarvinSketch to determine protonation states and microspecies percentages at a specific pH? It is possible to do this with Dimorphite_DL, but it does not list the percentage of microspecies at the desired pH.
