Otherwise I have to say I'm quite impressed with the responsiveness of the interface and the speed of the IMAP connection. Scailer is much more performant than Mailbird, which I currently use, and that in turn is much faster than Thunderbird and derivatives that I used before. So, great work on that.

I'm missing an option to define how many messages to download, and which IMAP folders to watch. The defaults seem to work for now, but I don't feel in control.

Thank you for the good words), we are glad that Scailer is working significantly faster for you than other email clients. We tested Scailer with email accounts with 500,000 - 1,000,000 email messages, and it works fast. Due to this Scailer has no option for limiting the count of messages to download. Yes, it may be a bit unusual that Scaler does not require customization, creation of folders and manual control. The application should automatically sort messages by contacts and robots and save user's time. Users can control where messages are displayed: in “Contacts mail”, “Promo and robots” or only in messages of a particular contact.

Woke my computer from sleep today to find Scailer running in the background with no visible indicator other than taking a lot of power as per Task Manager. I don't recall setting it to run in the background, and found this surprising. I would expect either a task bar or notification area icon.

Scailer should not work in the background until you change the option "Minimize Scailer on close" in the Settings -> General settings (do not forget to save settings). By background we mean working without a window. Also, Windows suspends running applications when you put the computer into sleep mode. You have full control of background work. High power utilization may be related to the initial downloading of a large number of messages from your email account. Later Windows should recalculate these statistics.
