Request for an update button

[mickeyseo]

Could you please add an update button to the program? You sometimes upload updates to this program, but I have to visit your repository in order to download the latest version.

In case you might consider implementing auto-update, I'd like to recommend Squirrel. I've seen good results with it.

I didn't have to abandon Inno Setup, either. I modified my script to use Inno as a self-extractor, basically a wrapper around Squirrel's Setup.exe. (The SetSquirrelTemp procedure sets us up for specifying the installation folder. Squirrel's default is %LocalAppData%\MyApp, which may be undesirable in some cases.)

; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!

#define AppPublisher "InteXX"
#define AppExeName "MyApp v"
#define AppVersion "1.0"
#define AppName "MyApp"
#define AppUrl "https://www.MyApp.com/"

Follow-up and cautionary note for the above recommendation: Even though we have the SetSquirrelTemp construct, Squirrel doesn't support installing to directories that require UAC approval.
