First impression IDE 2.0


just downloaded:

Version: 2.0.0-beta.12
Date: 2021-11-30T10:47:59.437Z
CLI Version: 0.20.1 [abb21449]

Copyright © 2021 Arduino SA

First impressions:


  1. HUGE improvement over version 1
  2. looks fancy enough
  3. Smooth experience (Don't know how you did it, but the IDE "feels" better than the old one when using, maybe bc I'm used to vs code though)


  1. Took a while to enable autocompletion
    a) The option is displayed prominently, but for me it was hard to find, because of the name "editor quick suggestions" when skimming for "autocomplete". Also in other IDEs I used, it was enabled by default
    b) unfortunately, first google result only tells you to add a board.:
    c) The missing info luckily can be found in the second result:
  2. Dark mode is enabled by default, but switches to light when clicking "OK" after changing settings. Will do a reinstall later to test if it didn't happen by accident.
  3. On Thinkpad T480s takes nearly a minute for startup


  • Make Autocomplete easier to enable, e.g. by editing 1.b) and including information from 1.c)
  • tbc


  • Can't wait for the 2.0 release version to make version 1 obsolete
  • Only small inconveniences, which might be personal preference of mine

Kind regards!

Thanks for your valuable feedback @obel_ix!

The tutorial was written prior to the current "editor quick suggestions" preference implementation, and never updated. I have notified the tutorial author about the problem.
