Against my better judgement, here's 0.900. It's got lots and lots new, but mostly the new shiny is the editor.
You can indent your code, you can edit it inside the listing window. You can use the Direct Command window just the same as you used to - but do read the supplied Readme file first for important control key changes! Oh, you can also cut, copy and paste code to and from the listing window.
It's not been extensively tested, so please, PLEASE report bugs if you find them!

Here's the What's new:
v0.0.0.900
==========
NOW IN 64BIT! SpecBAS32.exe and SpecBAS64.exe are newly available. The 64bit version is experimental, so feedback will be nice 
NOW IN OPENGL! Using OpenGL in selected binaries (marked -gl) to display the screen, reducing the workload on the CPU.
Added:
Added word (or rather, "line") wrapping. The direct command window can be used as it used to now, and lines will be forced to fit. Change the EDITORWRAP sysvar to enable/disable it.
DeleteAll banks no longer removes system banks unless SpecBAS quits - preserves keyclicks.
Added colour capability to POLYLINE/POLYGON with an array as a parameter
Added particle engine - PARTICLE array() FRICTION n GRAVITY m,o
Added radius to PLOT Array() handler in Array(n,4)
Added INVERSE, ITALIC, BOLD and TRANSPARENT 8 - leave them as they are, same as Sinclair BASIC
Changed Ctrl+Up/Down to jump to line starts prev/next
Added Ctrl+Backspace/Delete for deletion of words
Added F9 (run) and F10 (goto) hotkeys
Added ITALIC and BOLD commands. PRINT embeddable, but BOLD is only for mono fonts.
Added RENUMBER and DELETE handlers to the new editor.
Added Listing reordering on CTRL-R.
Added new editor, supports indentation and split lines.
Further CPU reductions.
Reduced idle CPU usage due to mouse moves triggering screen updates.
Optimisation to IF/ELSE addressing string characters
Reduced CPU usage when idle and during the editor quite significantly
Fixed problems with using compound assigns in numeric arrays
OVER 11 - Recolour mode. Any pixel that has a value of 0 gets the current PAPER colour, otherwise INK
WINDOW FLIP id and WINDOW MIRROR id added - They do exactly what they say they do
GRAPHIC FLIP and GRAPHIC MIRROR now also take a stringvar which, when containing a valid graphic, will flip and mirror it in-place
Compound operators (+=, -=, *=, /= etc) can be used in expressions - LET b=a+=1 will add 1 to a and then assign the result to b
MAT INTERP a(),b() TO c(),amount interpolates values of two similar arrays by a certain amount into a third array
INTERP(start,end,amount) function interpolates between start and end by the amount (0 to 1)
You can now use the {} characters to create comments inside a line
Short-circuit boolean evaluation for numeric AND/OR speeds up condition testing
BINV(n,m) and BREV(n,m) invert (or reverse the order of) m lower-order bits in n
INPUT ERROR now takes an optional REPEAT keyword to re-do the INPUT when an error occurs
64bit and 32bit builds display their bit-types on the title bar, along with FPS information
You can now use the ";" character to repeat a keyword with new parameters - e.g, CLS 1;2;3;4;5;6;7 will issue 7 CLS with different colours
64Bit-specific optimisations to many operations (mostly graphics, but memory filling and allocation too)
Loading a program automatically changes the directory to the file's location (not for MERGE)
A new, faster and more accurate quadratic bezier curve algorithm for the CURVE routine - demo "ultraviolet" looks a lot better
Added the POLYLINE keyword - works as for POLYGON, but SpecBAS doesn't close the polygon
Added array parameters for DRAW array() and DRAW TO array()
Some nice animations to opening/closing of the editor windows
Key buffering in the editor so that fast typing isn't lost
New Splash-screen and startup sound The old one used to crash on NEW with small window sizes
A totally new method of doing screen updates lets us get really smooth graphics, at any frame rate
The ? symbol can now be used instead of PRINT
Due to popular demand, LET is now optional - though you can still use it if you like
Inline inc/dec/mul/div to LET - LET a+=10 to add 10 to a. Also for -=,*=,/= -and- %= (mod) ^= (power) &=,|=,~= (AND/OR/XOR)
The editor now ignores font scaling for UI elements, looks better for non-square editor fonts
DIM SPLIT can now split on multiple characters
