As many have said previously I am absolutely fascinated by this synth.After I got Icarus, I spent around 4 to 5 hours a day for the next 5 weeks playing with it and completely ignoring all other plugins. I literally had to cut down on using it because it was becoming a mini addiction.

Now these long hours have resulted in quite a long list of feature requests and feedback, so here we go:
When hiding / showing the plugin interface, it defaults to displaying the arpeggiator. I’d like it to remember the view it was on last, E.g. Mod Matrix or Effects etc.
I would like to see the Shape knob on the Envelopes affect the Attack curve just as it does the Decay and Release.
Preset Specific :- Like others have mentioned, a search option in the browser would be very useful.
Also the ability to click a tag and view a list of presets by author, sound category etc.
- Ability to Rename Presets. (through right click or double click.)
- A Refresh button in the browser to re-read the patch file structure without quitting & restarting the plugin. This would be especially useful for saving & re-saving new patch presets that has been just created within the same instance or another instance of the plugin (without having to offload then reload the plugin).
- Ability to save Presets for Modulation Matrix status, - can be helpful to recall recurring / commonly used setting such as Key to Volume or Velocity to Filter envelop OR to copy settings from one preset to another.
Fix some display update issues :- Envelopes don’t update at all when controlled via midi, but can also fail to update when double clicking knobs to snap back to default value.
- Effect parameters don’t always light up or dim when effect is enabled / disabled, until mouse pointer hovers over them. This occurs more frequently when all three effect slots are used.
- Oscillators 2 & 3 displays also sometimes don’t show the waveform when switching from one patch to the other, until you click on their screen area.
ARP Specific :- Set Arp velocity by sweeping.
Right now, each velocity step can be set individually but velocity rises and falls have to be set step by step. For smooth sweeps it would be nice to drag across the steps and have the velocity sweep smoothly.
- Having velocity steps displaying for all 32 arp steps, whether a note is present on that step or not, makes it difficult to view the velocity pattern. It would be good to hide or dim the velocity marker if no note is programmed to play in that step.
- Arp latch or hold option. Not sure if that is already present but I might have missed it ?!
- Arp feature “rotate one step” and “shift notes up/down” are very useful but having to go through a menu to do this, can be very tedious, especially if you need to do it 4, 6, 8 rotations etc. Suggest horizontal and vertical scroll bars that can be easily dragged instead ??
Keyboard shortcuts.I understand this could be complicated because of possible conflict with DAW keyboard shortcuts. However, there are a lot of menu options in Icarus and keyboard shortcuts would do wonders for workflow. Preset change with Control+right & left arrows for example, or Quick save Patch with Shift +S etc.
Finally

Hide or remove floating tooltips and show their information on the preset screen underneath preset name (as in Saurus). This would make it far easier to consistently see the info in one place. It would also solve the problem of the data values often being hidden underneath the mouse pointer or in my case of poor eyesight, allow the use of a larger font to display the parameter value.
Thank you.
