IMPROVED FEATURE REQUEST ENTRY, re: In "hidden features" discovered in Resolve 14 3 COLOR page:
• Timeline "Mark In" and Timeline "Mark Out" setup is ghosted out in the MARK menu of this page but the feature does work via keyboard shortcuts I and O, respectively...
• Therefore, setting up a "user-definable" Timeline In to Out LOOP range, utilizing the hidden Mark In/Out feature is also doable...
• As well, although PLAYBACK menu Play Around To > Play In to Out mode is ghosted out in the COLOR page, this feature is also actionable, even in the case of a user-defined (custom) Timeline In to Out range, referenced in the first bullet-point just above.
I propose new Resolve versions should give those hidden features conspicuous access, with the GUI improved thusly:
1) In the COLOR page, provide a Zoom in and out capability to the Timeline Viewer's Scrub Bar, as we have in the EDIT page Source Viewer's Scrub bar.
2) In the COLOR page, provide a visual "In to Out Timeline Range indicator on the Timeline Viewer's Scrub Bar (such as we already have in the COLOR page Timeline Display, just below, in Resolve 14.3 but ☡ Note: Zooming in on this Timeline Display may be required, to make the range indicator visible
3) "Unghost" any pertinent menu items relative to making the above feature improvements (e.g., in Resolve 14.3, the entire top 50% of the MARK menu is utterly ghosted out, although we can indeed create a Timeline In and Out range (this feature is not apparent anywhere in the COLOR page GUI, rendering it a "hidden feature" -- so then, please...
3a) Unghost "Mark In" I -- and also unghost "Mark Out" O within the COLOR page MARK menu.
3b) Unghost "Play In To Out" Alt+/ in the COLOR page PLAYBACK menu, because it currently is indeed a working, though "hidden feature"
4) Force the Auto Clip Selector to default to the top-most, enabled video clip in the COLOR page, just as we already have in the EDIT page.
Stop.

Current Situation in Resolve 14.3
Here's how to set up a "User-defineable Timeline In to Out" range, which can be Looped accordingly:
Despite the ghosted out MARK In and Mark Out menu functions in COLOR page...
Step A: Ensure that LOOP is *not* engaged
Step B: Hit "I" to set a Timeline "In" point and "O" to set Timeline "Out" point.
Your custom Timeline In To Out settings are visible in the COLOR Page Timeline display, though you might need to zoom in on the Timeline display to notice it's there.
Step C: Hit the Timeline Viewer's LOOP gadget Ctrl+/ (Cmd+/ on Mac).
*Immediately* your "invisible COLOR page Timeline Loop range" will repeatedly Play, had the Play mode already been in process through the above 3 steps. if not,
Step D: Hit PLAY for the custom Timeline In/Out range to play.
IMPORTANT: No matter where you subsequently attempt to Play Timeline footage in the COLOR page now, you're forced into repeated playback of that "Custom Timeline Loop range" until you disengage the LOOP gadget ( Ctrl+/ ).
Disabling your custom Loop range will then cause RESOLVE )'s COLOR page to default back to auto-selecting (and indicating the In to Out range of a video clip that's near the Playhead...
This COLOR page clip auto-selection seems to me to be arbitrary, as it does not always auto-select the top-most enabled video clip -- and is cause for my last Feature Request item listed in point "4)" above.
